Architect/Analyst for designing a universal ERP/CRM (Retail + Distribution)

Budget: 200 USD Deadline: 1 day

Alexander, the task fits perfectly with my experience in web services and ERP-like systems. I will help break down the CRM into a functional architecture: a universal PIM with dynamic attributes, B2B distribution, B2C/POS, and a warehouse with movements, returns, and inventory. I would also think separately about roles, access rights, statuses, and "smart" scenarios to ensure the system is flexible and not overloaded. I can compile a detailed technical specification for the developers and discuss the logic of the modules.

Budget: 5000 USD Deadline: 30 days

Hello.
We have reviewed the task. According to the description, it is not just about a CRM, but about designing a universal trading platform with elements of PIM/ERP/CRM/POS and the ability to adapt to different types of businesses.
The idea of a universal feature builder and simultaneous support for:
— B2B distribution;
— retail;
— warehouse logic;
— custom types of goods;
— dynamic business processes is particularly interesting.
We are engaged in the development and implementation of CRM/ERP systems for companies with complex process logic and non-standard requirements. Among our clients are manufacturing companies, distributors, retail chains, and companies with a large number of custom business processes.
We have practical experience in:
• designing CRM/ERP architecture;
• building universal catalogs and entities;
• implementing warehouse and logistics logic;
• developing B2B and dealer cabinets;
• integrations with external services;
• designing systems for further scaling and customization.
In your case, it is important not just to describe tables and relationships, but to immediately consider:
— scalability of the architecture;
— flexibility of the data model;
— performance;
— access rights segregation;
— the possibility of further development without rewriting the core of the system.
We can also offer not only the development of technical specifications but also a comprehensive approach:
• audit and decomposition of business logic;
• architecture design;
• preparation of technical documentation;
• further development and implementation of the system.
From experience, the combination of "analytics + architecture + subsequent implementation" usually yields better results than writing technical specifications separately without the involvement of the future development team.
We are ready to join the discussion, help shape the system architecture, and propose the optimal approach to implementation. Expand

I have a system with the described functionality (and we can adapt and launch it right now), which has a framework for quickly organizing business processes. Many industry solutions have been created and operated for clients, from warehouse to retail store, HORECA, and manufacturing. It has its own report generator for CRUD forms and grids based on XML files / logic in CLOB fields of the database. Integration with trading equipment - scales / barcode scanners / data collection terminals / fiscal registrars and POS printers.

Hello Alexander,

I wouldn't set fixed product fields because for jewelry, electronics, food, and other categories, the parameters will be different.
The correct logic would be:
categories of products;
a set of attributes for each category;
types of fields;
mandatory and optional characteristics;
units of measurement;
validation of values;
templates for product cards;
inheritance of characteristics from category to subcategory.

For example:
jewelry: metal, purity, weight, carats, size;
electronics: brand, model, capacity, power, warranty;
food: fat content, expiration date, weight, storage temperature.

This will help add new types of products without modifying the code each time.

I also have previous experience working with a warehouse system, so it's much easier to identify all the pitfalls right away.

I will send the complete technical specification after payment on the platform, so if the price is acceptable, you can reply. Expand

Hello, I understand that you need a system architect or business analyst to create a universal CRM/ERP. The task is complex and involves designing four key modules with flexible logic that will adapt to different types of products. First of all, I plan to conduct a detailed requirements analysis to accurately understand how to implement dynamic characteristics in the catalog, properly set up accounting in distribution, and integrate functionality for retail.

My vision for implementation involves creating a clear logical structure that will take into account all business processes. This will include descriptions of tables, relationships, as well as the necessary diagrams for the four modules. It is also important to ensure convenient access to the system for various users to minimize the risk of errors in accounting.

However, there are several points that require clarification: how do you plan to integrate with existing systems? What level of access will be necessary for different categories of users? Without a sufficient understanding of these aspects, there may be risks in the project's implementation. I suggest we agree on the details to start work and create a clear action plan.

Budget: 2000 USD Deadline: 15 days

I am looking for a system architect or business analyst to develop the logical structure of a custom CRM system. The system should be a "constructor," adaptable to any type of product (from jewelry to electronics and food).

It is necessary to design 4 key modules:

Universal catalog (PIM): Logic of dynamic characteristics. The system should allow the user to create fields themselves (for example: "weight/carat" for jewelry, "capacity" for batteries, "fat content" for milk).

Distribution (B2B): Working with a network of retail outlets (wholesale). Accounting for orders, shipments, routes, and settlements with partners.

Retail (B2C/POS): Functionality of the retail outlet. Quick sales, stock balances on-site, logic of returns, exchanges, and loyalty programs.

Warehouse and Logistics: Accounting for movements between the central warehouse and sales points, inventory, write-offs, and handling returns.

What I expect from you:

Not code, but functional architecture (description of tables, relationships, and business processes).

Experience in creating trading or warehouse systems.

Suggestions for "smart" functionality from your experience (how to simplify life for the business).

Result: Detailed technical specifications for developers (logical diagrams, description of modules, and access rights). Expand

Budget: 1500 USD Deadline: 16 days

Good day. I have worked with such systems, so I can briefly outline how I would approach each module.
PIM with dynamic characteristics - here the choice is between three options: pure EAV (flexible, but slow on filters and search), JSON fields (simple, but limited in volume), hybrid. I recommend the hybrid: common fields (brand, price, barcode) in regular columns, categorical (weight, capacity, fat content) in JSONB with category templates. Plus a search index (Elasticsearch or Meilisearch) separately. This allows adding new categories without changing the schema and does not hinder speed.
B2B distribution. What is often overlooked in the specifications: multi-level pricing (by counterparty, customer group, promotions), credit limits with aging of debt, routes tied to drivers and vehicles, agency sales when one manager oversees several points of sale.
POS. A Ukrainian nuance - fiscalization (RRO/PRRO) must be embedded at the architecture level, not as an add-on. Plus offline mode (internet in stores drops, sales must continue with later synchronization), returns tied to a specific receipt, loyalty program as a separate contour because it often outgrows the POS itself.
Warehouse. Multi-warehouse accounting with reserves (goods shipped but still in transit - a separate entity), batch accounting (FIFO/LIFO by type of goods), inventory through mobile scanning with reconciliation of discrepancies.
I see the work process as follows:

- BPMN diagrams of key scenarios
- ER models for each module
- Role and access rights matrix (RBAC)
- Integration map between modules and external systems
- Consolidated specifications for developers

3-4 weeks of work. I will provide the exact cost after a more specific specification, as the price heavily depends on the volume of integrations (1C, fiscal, bank-client, marketplaces).
I can create a free sketch of the PIM module architecture (table schema + case "add a new product category") so you can see the level of detail.
If you have questions, I will be waiting in private messages. Expand

Budget: 400 USD Deadline: 14 days

Most analysts either create beautiful diagrams without understanding real business processes or dive into technical details, forgetting about the logic of how people work within the system. I work at the intersection of business processes, architecture, and development. This means that the final technical specification will be understandable not only to the programmer but also to the business owner and the manager who will work in the system every day. A universal catalog with dynamic characteristics is a non-trivial task. Incorrect architecture at this stage leads to a cumbersome system that cannot be scaled. I design PIM through Entity-Attribute-Value or JSON schemas with validation, depending on performance and flexibility requirements. B2B distribution with routes, settlements, and shipments requires clear logic for statuses and access rights - this is where most systems "break" during the growth phase. I embed this logic at the architecture level rather than fixing it later in the code. In addition to basic functionality, I will propose "smart" solutions from practice: automatic triggers for restocking, loyalty program logic without excessive complexity, and a role-based access model with granularity down to the operation level.

Work plan:
Immersion in business logic:

Interviews for each of the 4 modules
Clarification of product types, user roles, and work scenarios
Determining priorities and boundaries for the first version of the system

Designing module architecture:

Logical schema of tables and relationships for PIM with dynamic fields
B2B architecture: orders, shipments, routes, settlements
POS logic: quick sales, inventory, returns, loyalty
Warehouse module: movements, inventory, write-offs

Description of business processes and access rights:

Process map for each module
Role model: administrator, manager, cashier, logistics, partner
Description of boundary scenarios and exceptions

Preparation of the final technical specification:

Logical schemas in a readable format
Description of each module with data examples
Recommendations on the stack and stages of development. Expand

Hello

If the technical specifications are with hands, then no, but I can do the technical assignment

The rest is mine, number 22, constructor
Plus I understand the logic of CRM

For what period is the collaboration?

Budget: 300 USD Deadline: 3 days

I created 2 CRM systems for inventory management, and for each, I wrote the architecture: one for tire fitting and retail sales, the other for jewelry retail points for sales.

Additionally, your system needs to incorporate sales logic and accounting, as well as inventory management, so that the system operates quickly when the business has data for 5 or more years.

For sales, it is also worth considering staff changes and cashiers, which involves working with personnel, salaries, etc.

We can discuss the system in more detail in private messages; I would be happy to help.

Budget: 1500 USD Deadline: 30 days

Hello!
I can help with the descriptions of the architecture, think about how everything should function, and provide a complete block diagram of the database. Provide several options on which technologies can be used, along with the timelines for each technology, advantages, and disadvantages.

Budget: 1500 USD Deadline: 14 days

Hello! I am interested in your offer. I have over 3 years of experience in architecture and the development of complex systems (PHP/Laravel/Go), including projects in logistics and business process automation. I specialize in creating flexible data structures, which is perfect for your request for a "builder system."
Why I am suitable for this task:
Experience in complex structures (PIM): I have developed systems with dynamic characteristics and multilingual support (for example, online library projects and transportation services). I understand how to implement the EAV model (Entity-Attribute-Value) or JSON schemas in a way that keeps them fast and user-friendly.
Logistics and Warehouse: I have experience in projects related to the automation of transport checks and enriching carrier data. I understand the business processes of shipments, routing, and inventory accounting.
Information security and control: I develop my own monitoring systems (Sentinel Monitor), which allows me to design flexible and secure access control models (RBAC).
My proposals for "smart" functionality:
Event-Driven Architecture: Implementation of a trigger system (like in my Sentinel project) that allows automating actions: for example, auto-ordering products from suppliers when critical stock levels are reached.
AI assistant for the catalog: Since I actively work with local LLMs (Llama, Mistral), I can design the logic for automatically filling in product characteristics based on photos or short descriptions via API.
Flexible reports: A builder not only for fields but also for analytics — allowing users to create their own dashboards with the necessary KPIs.
The result you will receive:
A complete ER diagram of the database (tables, indexes, relationships).
A description of the business logic for each module (Flowcharts).
A detailed technical specification for developers, written in a language understandable to both the business and tech leads.
I am ready to discuss the details and demonstrate the logic of my current solutions.
Best regards, Andriy. We can discuss the price after the full scope of the task is defined. Expand

Hello
My name is Dmitry
The task is clear — you need not development, but a well-thought-out architecture of a CRM as a constructor for different types of businesses. This is exactly the stage on which it depends whether the system will work or "break" when scaling.
My approach
First, I analyze the business logic (how the product, warehouse, and sales actually work), then I design the structure — tables, relationships, roles, processes.
What I will do
— Design a universal catalog (PIM) with dynamic characteristics (through a flexible attribute model)
— Describe the B2B module (orders, shipments, partners, settlements)
— Consider B2C/POS (quick sales, stock, returns, loyalty)
— Warehouse and logistics (movements, inventory, write-offs)
— Database structure (tables, relationships, keys)
— Access rights and roles logic
— Description of business processes (how data flows through the system)
— Recommendations for "smart" functionality (automation, simplifying work, minimizing errors)
I have experience working with CRM, warehouse, and e-commerce systems, and I understand where problems usually arise (especially with universality and scaling).
Result
A complete technical specification for developers:
Clear architecture + diagrams + module logic
I am ready to discuss your case in more detail and propose an optimal architecture for your type of business 👍 Expand
