System Integration: ERP, CRM, Website and Marketplaces

System integration without replacing what already works: your ERP, CRM, website, phone system and marketplaces exchange data on their own, and managers stop re-typing it by hand. The first integration from $4,900 in 2–3 weeks, a free integration map in 3–5 days

When it matters

Situations where we help

If you recognize even one, we can be useful

01

Your CRM knows nothing about the warehouse, and accounting lives apart

Every system is an island. The boss pieces the picture together from 5 sources, the numbers drift apart by lunchtime, and decisions get made on yesterday's figures.

02

Staff spend 2–3 hours a day copying data

From Excel to the accounting system, from the CRM to email, from the request form to the ERP: every copy-paste is a chance for mixed-up SKUs, wrong amounts and lost orders. Do the math: two managers × 2 hours a day is about 80 person-hours a month spent moving data by hand.

03

The last sync broke after an ERP update

A freelancer wrote an export script, it worked for six months, then the system got updated and orders stopped coming through. You found out from a customer whose shipment never arrived. Nobody remembers how the sync works: no documentation, no logs, no one to ask.

What you get

Features and benefits

Concrete results we deliver for you

01

ERP, accounting and CRM: two-way sync

Invoices, stock, orders and payments sync both ways in real time. Conflicts get resolved by your rules: which system owns the stock count, what to do when the numbers don't match. Zero drift: the data is current in every system.

02

Amazon, eBay and Etsy in one window

Catalogs, prices, stock and orders sync with all your marketplaces automatically. A price update takes 5 minutes instead of 2 hours, and cancellations caused by SKU mix-ups drop to zero.

03

We don't modify your ERP's core

The sync lives in extensions and APIs, not in edits to the system's standard objects, so your ERP stays on vendor support and updates normally. Development happens on a copy of the database; we don't touch your live system.

04

Peak loads don't take the sync down

A message queue with guaranteed delivery, automatic retries, a log of undelivered messages. An overnight catalog repricing or a spike in orders doesn't lose a single message.

05

An open API: partners connect on their own

A REST API with documentation, rate limiting and versioning. An external partner connects in 2–3 days on average, instead of a month of back-and-forth emails.

06

Equipment and sensors are data sources too

Scanners, machines and sensors plug into the same data flow. In the ProControl case, scanners on four lines send output to the system and to Bitrix24: 100% of production is accounted for without manual entry.

Process

How we work

A transparent process with clear stages and deliverables

1
Stage 1

Integration map: 3–5 days, free

After a 30-minute call, we show you a map: what systems you have, where data is moved by hand and what that costs in hours. We check what your systems' APIs actually return, using the documentation and a test environment, with no access to your live database. You keep the map, whatever you decide.

2
Stage 2

Sync architecture and a fixed quote: 3–5 days

We sign off on the data mapping, conflict rules, formats and protocols, and the rollout plan. The quote is fixed in the contract before development starts.

3
Stage 3

The first integration in production: 2–3 weeks

Connecting your ERP to a website, CRM or marketplace takes 2–3 weeks; setups with WMS, MES and equipment take 4–7 weeks. Development on a copy of the database, load testing at up to 10× your current volumes.

4
Stage 4

Switched on one at a time, with rollback

We activate the syncs one channel at a time: reading first, then writing. For the first week, the data is checked against manual entry. Health checks, alerts in Telegram and a log of every message: the monitoring stays with you.

Cost and timeline

What it costs

Cost
from $4,900
What's included
  • Start free: an integration map in 3–5 days. What systems you have, what data moves by hand, what to connect first
  • One integration in production (ERP ↔ CRM, website, phone system or marketplace): from $4,900, 2–3 weeks
  • ERP ↔ website or B2B portal sync with catalog, prices, stock and orders both ways: from $9,900, 3–5 weeks
  • A setup of 3–5 systems with a queue, retries and monitoring: $19–45K, in stages
  • We don't modify your ERP's core: extensions and APIs only. The code, access and documentation are yours

The final cost depends on scope. We'll work it out after a short call.

Prices shown are indicative and for information only; they are not a binding offer. The final cost is set in the contract once the project requirements are agreed.

System integration: data moves between your ERP, CRM and website on its own

We don't replace what already works for you; we connect it. We start for free: in 3–5 days, an integration map shows which data your managers re-type by hand and what to connect first. One integration in production costs from $4,900 and takes 2–3 weeks, a sync between your ERP and a website or B2B portal starts at $9,900, and a setup of 3–5 systems runs $19–45K, in stages. The price ranges for every service are on the pricing page. We don't modify your ERP's core: we use extensions and APIs, so updates don't break anything.

To be upfront: if the task is a standard store-to-accounting sync or an off-the-shelf export connector, it's cheaper to buy the connector or hand the job to your in-house admin, and that's what we'll advise. We broke down the sync options and what each one costs in our article on connecting 1C, a popular ERP in Eastern Europe, to a website.

Proof with numbers. SHATE-M: 1C via REST API and a catalog of 500,000+ items, with dealers placing 70% of orders online on their own. ProControl: scanners on four lines send output to the system and to Bitrix24, so 100% of production is accounted for without manual entry. Revizor: an add-on on top of Bitrix24 that doesn't replace the off-the-shelf CRM, with 100,000+ calls analyzed by AI.

There are dedicated breakdowns for specific needs: integration for online stores, for logistics and for manufacturing. The automation ROI calculator estimates the payoff in hours and money. If what's done by hand is the process itself rather than moving data, see business process automation; if your off-the-shelf CRM no longer cuts it, custom CRM development; if you have no systems at all and need one connected setup, a modular ERP; if you need to connect AI to your data rather than systems to each other, AI integration.

ERP modernization and a B2B portal for an auto parts distributor

Auto parts and distribution

Experience from our CTO's portfolio: ERP modernization and the launch of a B2B portal for a large auto parts distributor with a catalog of 500,000+ items. 1C (a popular ERP and accounting platform in Eastern Europe) connected via REST API, search by VIN and cross-reference numbers through TecDoc, dealer accounts with personal pricing. The project was completed before March Code was founded.

70%of orders go through the portal
500K+catalog items with VIN search
into 1Corders arrive with no manual entry

«Dealers stopped calling managers to ask whether something is in stock: they see the stock in the portal themselves. An order takes minutes and goes into 1C without anyone retyping it. Within a year, 70% of our total turnover went through the portal, and that changed how our sales department works.»
