CRM customization and integrations with accounting systems

When the packaged product almost fits but 10–20% is missing — we add it. Bitrix24, amoCRM, telephony, marketplaces, 1C integration. Carefully, reversibly, update-friendly.

What we'll build for you

What's included

Bitrix24 cloud customisation (REST)

Local apps, webhooks, custom fields, business processes, robots. Everything available via the REST API — without touching the core.

Bitrix24 self-hosted customisation

Custom modules, business processes, event handlers, custom components. Built so platform updates don't break your customisations.

amoCRM customisation

Widgets, deal-card extensions, API integrations, custom analytics and sales-scenario automation.

1C ↔ CRM integrations

Two-way sync: items, accounts, documents, stock, payments. 1C-side work is done by 1C franchisees; we own the integration layer.

Telephony & marketplace integrations

Virtual PBX, chat-bots, messengers, Ozon / Wildberries / Kufar — connected to your CRM so managers don't switch tabs.

Non-standard reports & analytics

When stock reports aren't enough — we build our own: SQL, dashboards, Excel exports, BI tools.

FAQ

Frequently asked questions

Do you customize 1C?

No. 1C customization is done by 1C franchisees — that's their specialization and certification. We are responsible for the integration of 1C with your CRM or custom system: data exchange, document sync, automation at the boundary.

Won't the customization break Bitrix24 updates?

No. For the cloud we use REST and local apps — they don't depend on core updates at all. For self-hosted we build our own modules and event handlers — the path Bitrix recommends, and it survives updates.

Can we do this ourselves using your instructions?

Simple scenarios — through standard settings or the Market — often yes. If the task is more complex (a custom business process, a non-standard integration, a custom report) — it's faster and more predictable to hand it to us than to figure it out. We'll tell you honestly at the brief.

How much does customization cost?

It depends on complexity. A typical customization — 1–3 fixed-price sprints. At the brief we decompose the task and quote the amount before work starts — no "extras coming later".

Do you work with amoCRM the same way as with Bitrix24?

Yes. amoCRM has a solid API; we build widgets, extensions, integrations and automations. At the brief we'll tell you which CRM solves your task with less customization — we're not tied to a particular vendor.

What if I need an integration the market doesn't offer yet?

That's our profile. If the system has an API — we'll build the integration. If there is no API — we discuss workarounds (exports, parsing with permission, RPA). We'll tell you realistically what will work.
