Setting up Cookie Consent and Consent Mode v2 on OpenCart websites

Budget: 8950 UAH Deadline: 3 days

Hello! I saw the task — OpenCart + Cookie Consent + Consent Mode v2, and immediately understood the essence. This is not just about "hanging a banner," but correctly linking user consent with GTM so that Google Ads and GA4 accurately transmit the consent status to Google.

What I will specifically do:
• I will install and configure the Cookie Consent banner (Usercentrics / Cookiebot / OneTrust — your choice)
• I will set up Google Tag Manager for Consent Mode v2 — so that GA4, Google Ads, Conversion Linker tags respond to the user's choice (grant/deny)
• I will link consent with Google Ads tags (conversions) and GA4 (events,/page_view)
• I will check through Tag Assistant whether the consent status is correctly processed

⚙️ Details: OpenCart has its specifics — the template is often custom, and the placement of GTM scripts can be in header.tpl or through a module. I will navigate this trick without conflicts with current plugins.

Stack: GTM + GA4 + Google Ads + Consent Mode v2 + OpenCart. I have done this on OpenCart before — the main thing is not to break current conversions and set up default consent correctly.

Experience: I had a similar case — after implementing Consent Mode v2 on a client's store, the transmission of conversion data to Google Ads was restored without loss of Modeling.

I am currently completely free — I will take your project and devote all my attention to it, starting today.

To get started, I need access to GTM and the OpenCart admin panel (or FTP). Write to me — and I will draft a plan for the first stage in 10 minutes. Expand

Budget: 18000 UAH Deadline: 5 days

We can take full setup for 3 OpenCart websites. The timeframe is 5 working days, budget - 18,000 UAH, if there are no non-standard advertising scripts or heavily customized themes.

For implementation, I would go not through a cosmetic banner, but through a proper consent management scheme - CMP or a light custom solution, cookie categories, default denied until user selection, updating consent status in Google Tag Manager, checking transmission in Google Analytics 4 and Google Ads. Here’s the nuance - the banner should not just be displayed, but actually block or allow tags by categories.

> Access will be needed to OpenCart admin panels, Google Tag Manager, Google Analytics 4, Google Ads, and, if available, to the current CMP or cookie module.
> After setup, we will provide a brief technical report - what has been changed, which events and tags have been checked, what should not be touched manually to avoid issues, as this can happen =/

I would like to clarify 2 points:
> all 3 websites have the same OpenCart theme and the same set of tags.
> Google Tag Manager is already installed on each site or does it need to be set up from scratch?

Similar experience in e-commerce and system analytics:

> https://business.ingello.com/prime-eva - more complex logic for retail, where data accuracy and system behavior are important.
> https://systems-fl.ingello.com/ua - briefly about our approach to such tasks.

Overall, a reasonable scope for a separate technical phase. The main thing is not to create another informative banner that looks nice but does not manage anything. Better less shine, more proven logic - as they say, measure seven times, connect once. More precisely, I might be getting too formal, but that’s the essence =) Expand

Budget: 27000 UAH Deadline: 14 days

I can implement a full Cookie Consent and set up Google Consent Mode v2 on three OpenCart sites. I will install a compatible CMP, integrate it with GTM so that consent statuses are correctly transmitted to GA4, Google Ads, and other marketing tags, and ensure that tags are triggered only upon granted consent. I will pay special attention to the proper filling of the dataLayer and the "default deny" scheme for tags in accordance with GDPR and Consent Mode v2 requirements. First, I will check the current banner, GTM container, and list of tags. Can you provide access to the admin panel and GTM?

We already have a practically ready similar solution for Cookie Consent and Google Consent Mode v2, which can be quickly adapted for OpenCart on 3 sites and launched, I'm here in the correspondence.
We can take the turnkey setup in 5 working days - CMP or another solution for consents, a banner with acceptance, rejection, and categories, transferring consent status to Google Tag Manager, Google Analytics 4, Google Ads, and launching tags only with permissions.
Regarding the budget, the target is 18,000 UAH, if all sites have the same OpenCart theme and access to the admin panels, Google Tag Manager, Google Analytics 4, and Google Ads is already available.
Look, there's a nuance - it's important to check whether the tags are currently set through Google Tag Manager or partially in the OpenCart template, as this affects the cleanliness of the implementation.
Please let me know if all 3 sites are on the same OpenCart theme and if Google Tag Manager, Google Analytics 4, and Google Ads resources have already been created.
One more question - is only basic blocking of marketing and analytical tags needed, or also a consent log and separate storage of consent evidence for GDPR?
