113 USD Connecting WABA to CRM: Step-by-Step Plan and Verification
Consulting
When a client hears "we'll connect official WhatsApp", they imagine something simple. In reality, WABA is a multi-step process with failure points, waiting periods from Meta, and business requirements that are not obvious in advance.
Grey WA (unofficial, Personal WA):
— the phone with the app must be constantly online — a single point of failure
… — connects as a linked device via QR code
— if the phone is off for more than 14 days — authorization drops, the channel disappears
— Meta does not notify integrators about updates — temporary outages are possible
WABA (official, white):
— no phone needed, works via API key 24/7
— the number registered in WABA is removed from the phone app
— the number becomes fully server-based, works independently of any device
First question to the client before the start: do you want to transfer the current number to WABA or set up a separate new one?
— Transfer is technically straightforward, but the number will leave the app permanently.
— A new number is easier to set up, but clients will receive messages from an unfamiliar phone.
— — —
Step-by-step WABA connection plan
Honestly: this is not 10 minutes like grey WA. Minimum 5–10 business days in a best-case scenario.
Step 1. Create a Meta Business Portfolio
The root company account in the Meta ecosystem — WhatsApp Business accounts and ad accounts are linked to it. Without it, WABA cannot be connected. A personal Facebook account with a real name and photo is required.
Step 2. Create a WhatsApp Business Account within Meta
Done through the website with Facebook authorization — the site guides you through the process step by step.
Step 3. Register a phone number
Transfer an existing number or register a new one.
Step 4. Display Name verification
Meta reviews the company name that clients see in WhatsApp.
Timeline: 2–3 business days. The name must match the real business name.
Step 5. Company verification in Meta
Timeline: 5–7 business days, sometimes longer.
Required: website, name match with Meta Business, possibly — registration documents.
Not guaranteed on the first attempt — rejection is possible and resubmission is allowed.
Step 6. Create templates and submit for moderation
Each template goes through a separate Meta review.
Timeline: usually 2–3 hours, sometimes up to 2 weeks.
Step 7. Top up the WABA balance
Payment is two-component: Wazzup subscription + a separate Meta balance for template messages. From 01.07.2025 — payment per each sent template message. Balance is charged automatically — do not let it hit zero.
Step 8. Set up CRM integration
Only after the channel is active and templates are approved.
— — —
Company verification and message levels
Before verification — Level 0: no more than 250 outgoing conversations per day. Incoming are unlimited.
After verification — Level 1.
Limits grow based on reputation:
Level 0: 250 / day
Level 1: 2,000 / day
Level 2: 10,000 / day
Level 3: 100,000 / day
Level 4: unlimited
The limit applies to the entire Meta Business Portfolio.
Two numbers with a combined limit of 2,000 — that is 2,000 total, not 2,000 each.
To reach Level 1: send at least 1,000 templates in 30 days (~33 new conversations daily) and receive few complaints from recipients.

113 USD WhatsApp: Grey or White — Which to Choose and When to Switch?
AI Consulting
When integrating WhatsApp with a CRM, clients always have one question: which WhatsApp should we connect? I address this in every project — here's the framework I use.
Terminology
Grey / unofficial / Personal WhatsApp — all the same thing: connecting via QR code or phone number, bypassing the official API
… White / official / WhatsApp Business API / WABA — all the same thing: Meta's official solution through authorised partners
Pros and Cons
Grey WA
+ Quick setup, no verification required
+ No restrictions on incoming messages, works from a personal number
+ Can message first without a template
— Instability: authorisation drops, phone must always be online
— Risk of being banned without warning during mass campaigns
— Meta doesn't announce updates — temporary outages affect all "grey" integrators
WABA
+ Official API — stable, no phone required
+ Mass campaigns via Meta-approved templates
+ Verified badge, increased brand trust
+ Tiers: from 250 to 100,000+ conversations per day
— Paid templates (from 01.07.2025 — charge per template message sent)
— Meta Business verification required — takes 1 week to 1 month
— Cannot message first without a template
Risks and Opportunities
Grey WA
— Risk: losing all conversation history if the number gets banned
+ Opportunity: fast launch with no upfront budget
WABA
— Risk: template blocked for violating Meta policies
+ Opportunity: funnel automation, chatbots, mass notifications without ban risk when rules are followed
When to Use Which
Grey WA is suitable if: team is up to 5 managers, no mass campaigns, limited budget, quick start needed, CRM is just being tested
WABA is suitable if: team is 5+ people, campaigns/notifications are needed, stability is important, business is scaling
When to Switch from Grey to White
— Number starts getting banned or receiving warnings from WhatsApp
— Mass campaigns are needed regularly (more than 100 contacts per day)
— Incoming leads (more than 100 per day) need templated messages sent to them
— Loss of conversation history when a manager leaves has become a problem
— Business has grown, a verified brand presence in the messenger is needed
How to Choose
Before connecting anything, I always clarify:
1. How many managers will be working in WhatsApp?
2. Do all managers use one shared number or each their own?
3. How many WhatsApp numbers do you plan to connect?
4. How many new leads do you receive per day?
5. How many enquiries from new and existing clients per day?
6. Are you planning outbound campaigns?
7. If yes, how often and to what size of audience?
8. Do you already have a number that has been used to communicate with clients?
9. Have you experienced any bans or warnings from WhatsApp?
10. Is brand verification (Meta badge) important to you?
11. What budget have you allocated for the messenger channel?
12. Is automation needed: chatbots, trigger messages?
Answers to these questions will help determine whether grey, white, or both channels simultaneously are the best fit for your situation.
Send me your answers in a private message and I'll help you choose the right WhatsApp connection type.
OR
Book a personal consultation and we'll figure it out together and help you connect the best option for you.

16 USD AI visualization of sneakers for teenage lifestyle content
AI Art
I was tasked with transforming ordinary product photos taken in-store into a dynamic lifestyle series for teenagers.
The main requirement was to maintain the product recognition of the sneakers: shape, design, texture, material combinations, lacing, contrasting black elements, mesh texture of the upper, and the intricate pattern of the sole. Due to the large number of small details and various textures, this case was technically more complex than a standard product image generation.
… The visual concept of the series is built around the idea of urban lifestyle: the sneakers are presented as part of an active teenage style in a big city. It was important to demonstrate the versatility of the model: it looks organic in both a boy's outfit and a girl's styling, pairing well with sportswear, casual looks, and even a dress.
As a result, a series of AI-generated images was created for social media, product carousels, advertising creatives, or product presentations. The series showcases the product in various scenarios: overall look, sports field, dynamics of movement, close-ups on feet, and details of the model itself.

3 USD Design of the main card for the NEXT-GEN VR headset (English/Russian)
Infographics
The task was to create a stylish cover for a next-generation VR headset in a strict, magazine style. It was important not to overload the image with unnecessary colors, but to emphasize the minimalism and premium look of the gadget.
What I implemented in this project:
• I built a deep monochrome background with soft studio lighting, on which the white headset body looks maximally voluminous and expensive.
… • To add dynamics to the frame, I carefully integrated floating controllers, adjusting realistic shadows and reflections on them.
• I made the main accent title large and strict in English, while all the key features of the device (PC connection, new lenses, hand control) were neatly translated and designed as concise icons at the very bottom of the slide.
The card turned out to be clean, aesthetic, and immediately stands out among the usual gaudy covers of competitors.

100 USD Landing page for a practicing psychologist
Website Development
A practicing psychologist needed a website that does not intimidate or pressure, but gently leads an anxious person to the first step — a free consultation. The complexity of the niche lies in the client's doubts: "What if my problem isn't serious?", "What if we don't match?", "Will this even help?" The website had to alleviate these fears and build trust in a specific person, rather than in a "service".
I built the structure around the client's journey from anxiety to the decision to sign up:
… - A personal first screen with a photo, name, and a warm description — we sell the person, not an abstract "psychological help";
- A services block with three formats (closed channel, webinars/courses, personal consultations) and transparent pricing — the client chooses the level of involvement that suits them and their budget;
- "How we will start working" — clear 4 steps that remove the fear of the unknown ("What will happen after I write?");
- A key block "how it is now — and how it can be": on the left, the client's pains in their own words, on the right — the desired state. This is the strongest technique — the person recognizes themselves and sees a way out;
- A trust block with numbers (6 years of practice, 2000+ hours of consultations, education, membership in an association) — proof of qualifications;
- Testimonials from real clients and an extensive FAQ that addresses the last objections;
- A final form with a soft, non-pressuring CTA — "sign up for a free consultation".
A warm earthy palette (terracotta + cream + dark graphite) instead of a cold "medical" look — creates a sense of safety and humanity, which is critical for the psychological niche. Neat typography, responsive design, a unified logic of CTA that consistently leads to one action.
A website that speaks the client's language and guides them from the internal "I probably don't feel that bad" to the clicked sign-up button. The structure works for trust and conversion, rather than just presenting the specialist.

401 USD Website for the brand "Sokoveya" — natural direct juice
Online Stores & E-commerce
Developed a website for the brand "Sokoveya" — a producer of natural cold-pressed juice in Uman and the Uman district.
The main task of the project was to create a clear and visually appealing website that presents the brand's products, helps sell juices online, accepts orders for fruit pressing, and attracts partners for collaboration.
… Within the project, the following was accomplished:
— development of the website structure;
— creation of a design in the style of a natural product;
— setup of the homepage;
— design of the product catalog;
— configuration of product blocks with the ability to add to the cart;
— creation of blocks for quick orders;
— design of the section about production and brand advantages;
— addition of a separate block for partners, cafes, stores, and HoReCa;
— creation of a block about the service of pressing juice from the client's fruits;
— setup of a FAQ block with answers to frequently asked questions;
— addition of contact information and a map;
— adaptation of the website for mobile devices;
— basic SEO preparation of the pages;
— preparation of the website for indexing in Google.
Special attention was paid to the page structure: the user immediately sees that they can buy ready-made juice, order pressing of their own fruits, or inquire about partnership collaboration. This helps the website function not only as a presentation of the brand but also as a full-fledged tool for sales and applications.
As a result, the client received a modern website with a product catalog, clear navigation, responsive design, trust blocks, and basic SEO preparation for further promotion.

11 USD Article about Korean cosmetics
Copywriting
Task: Writing an expert SEO article for an online store of Korean cosmetics (K-beauty). The goal is to write the text in a lively language with a friendly Tone of Voice, explain complex cosmetic terms in simple language, and structure the information by skin types.
Hyaluronic Acid or Ceramides: Which Sheet Mask to Choose?
… Hyaluronic acid and ceramides (ceramides) are two absolute hits in K-beauty. Both components promise to make the skin hydrated and beautiful, but they work quite differently. Let’s break it down without complicated chemistry to see what’s right for you.
Main Differences: How It Works
Hyaluronic acid is a true moisture magnet. Imagine it as a tiny sponge that instantly "hydrates" the cells. The result: the skin becomes plump, the Korean glow effect (healthy radiance) appears, and fine lines from dryness are smoothed out.
Ceramides are natural lipids that act as a reliable seal, preventing moisture from evaporating. They rebuild the protective barrier. The result: the feeling of tightness disappears, redness calms down, and the face becomes soft to the touch.
Which Component is Suitable for Each Skin Type
Dry Skin: Your best match is a sheet mask with ceramides. It will provide the necessary nourishment and create a protective layer.
Dehydrated Skin (even oily): Your best match is hyaluronic acid. It will provide powerful hydration without any heaviness.
Sensitive Skin: Ceramides. Their main superpower is restoring the skin barrier and reducing sensitivity.
Combination Skin: Hyaluronic acid is perfect for a basic routine, while ceramides can be used as a SOS mask once a week.
Advantages and Features
Hyaluronic acid provides an instant "plump skin" effect and has a lightweight texture. But remember the golden rule of K-beauty: always seal it with a cream to prevent it from drawing moisture from the skin itself.
Ceramides are a quick fix after peels or acids; they provide a deep sense of cozy comfort. However, their texture is often creamy, so for very oily skin in summer, it’s better to save them for the evening.
So When to Choose What?
Choose hyaluronic acid if: you need a quick freshness effect, your skin looks dull, and you want light hydration without shine.
Choose ceramides if: your face feels tight after washing, there’s flaking, or you are recovering from cosmetic procedures.
Conclusion
Listen to your skin. When you want lightness and radiance — reach for hyaluronic acid. And when your skin asks for protection and calm — go for ceramides. Alternate them and remember: the best care brings absolute comfort!
