Connect the business
API and system integration that makes your tools behave like one system
Most companies do not need another application; they need the ones they have to talk to each other. AutoProbaho designs and builds API integrations between the systems your business already runs on — ERP, CRM, accounting, e-commerce, WhatsApp, email, social channels, Google Workspace, Microsoft 365 and cloud databases — so an order, a payment or a customer message is captured once and flows to every place it is needed, with error handling and monitoring built in.
Every gap between two tools is filled by a person re-typing
The order arrives on WhatsApp, is typed into a Google Sheet, copied into the invoice template, entered again in the accounting package and finally announced in a group chat so the warehouse knows. Five systems, four manual hand-offs, and a customer waiting. Multiply by hundreds of orders a month and the cost is not just labour: it is late invoices, wrong stock, duplicate customers and numbers that never reconcile.
Off-the-shelf connectors cover the easy cases and stop at the edges — a field that does not map, a marketplace that only exports CSV, a bank that has no API, an accountant who needs a specific export format. Real integration work is in those edges: mapping data models, handling failures, deduplicating, respecting rate limits and making sure the connection still runs when a vendor changes its API next year.
Who this is for
- Businesses running three or more disconnected tools — ERP, accounting, e-commerce, CRM, messaging — with staff bridging the gaps by hand
- E-commerce and distribution companies syncing orders, stock and payments across marketplaces, shops and accounting
- Bangladeshi companies where WhatsApp, Facebook, bKash/Nagad and Excel are the de-facto operating stack
- German Mittelstand firms connecting CRM, ticketing and ERP with DATEV, lexoffice or sevDesk and Microsoft 365
Current pain points
Manual re-entry between systems
The same customer, order or invoice is typed into two or three tools; each copy drifts from the others.
Customer messages live outside the system
WhatsApp and Facebook enquiries never reach the CRM; follow-up depends on whoever holds the phone.
Stock and orders disagree
Shop, marketplace and warehouse each show a different quantity; overselling and cancellations follow.
Accounting is always behind
Sales and payments reach the accountant as month-end exports, so receivables and VAT are reconciled late.
Fragile scripts and one-off connectors
A quick integration built by a former employee breaks silently; nobody knows until a customer complains.
What AutoProbaho builds
Integration architecture
A map of every system, the data each owns, the direction of every flow and the source of truth per record type — agreed before a single connector is built.
REST / GraphQL / webhook integrations
Custom connectors using each platform's official API, with authentication, pagination, rate limiting and retries handled correctly.
Data mapping & transformation
Field mappings, unit and currency conversions, deduplication rules and validation so records arrive clean on the other side.
Middleware & event layer
Where several systems must exchange data, a lightweight integration hub (often n8n plus a queue) rather than a web of point-to-point links.
Monitoring, alerts & runbooks
Every flow logs what it did, retries what failed, alerts a named person on persistent errors, and is documented for your team.
Modules & capabilities
Google Workspace & Microsoft 365
Gmail/Outlook, Google Sheets/Excel Online, Drive/SharePoint, Calendar and Teams — mail-to-record, document generation, calendar sync and shared-drive filing.
WhatsApp, email & social
WhatsApp Business API, transactional email, Facebook and Instagram messaging — enquiries into CRM, order confirmations and status updates out, with opt-in handling.
E-commerce & marketplaces
Shopify, WooCommerce, Shopware, Daraz and custom shops — orders, stock levels, prices, fulfilment status and returns synchronised with ERP and warehouse.
Accounting & finance
Tally, QuickBooks, Xero, DATEV, lexoffice, sevDesk — invoices, payments, receivables and VAT posted automatically; exports in the accountant's required format.
Payments & banking
bKash, Nagad, SSLCommerz, Stripe, PayPal, SEPA statements — payment confirmation matched to invoices, reconciliation and dunning triggers.
ERP / CRM connectors
Two-way sync between custom or packaged ERP/CRM systems and every other tool — customers, items, orders, tickets and activity history.
Cloud database integration
PostgreSQL, MySQL, Supabase, BigQuery — consolidated data stores for reporting and BI, fed by scheduled or event-based pipelines.
Legacy & file-based systems
CSV/Excel drops, SFTP, EDI, on-premise databases and equipment exports wrapped in APIs so older tools join the landscape without replacement.

Implementation process
- 01
Integration audit
We list every system, its API capabilities, data volumes and the flows you need; we identify the source of truth per record type.
- 02
Architecture & mapping
Flow diagrams, field mappings and failure handling agreed in writing; build-versus-connector decision per integration.
- 03
Build & test in sandbox
Connectors developed against test accounts with real sample data; edge cases (duplicates, partial payments, cancelled orders) covered.
- 04
Controlled go-live
Flows switched on one at a time with parallel checks; historic backfill where required.
- 05
Monitor & maintain
Dashboards, alerts and a runbook; optional managed support to absorb vendor API changes.
Expected business outcomes
Data entered once
Orders, customers and payments are captured at the source and appear everywhere else automatically.
Faster customer response
Enquiries and confirmations move in minutes, not when someone gets to the phone.
Books that reconcile
Accounting receives transactions as they happen, with references that match.
Integrations you can trust
Failures are visible and retried; nothing breaks silently.
Security & ownership
Least-privilege credentials
Every connector uses its own scoped API key or OAuth grant, stored in a secrets vault, rotated on schedule and revocable in one place.
Encrypted in transit and at rest
TLS on every call, encrypted logs, and no customer data on shared third-party servers unless you choose that platform.
Compliance-aware data flows
GDPR/DSGVO data-minimisation, EU-region hosting where required, opt-in handling for WhatsApp, and audit logs for every synchronised record.
Frequently asked questions
A single well-documented integration (for example shop to accounting) is typically live in 2–4 weeks. A multi-system landscape with an integration hub is delivered in phases over two to three months, one flow at a time.
Whatever fits. For most SME landscapes a self-hosted n8n hub plus small custom connectors gives the best balance of cost, control and maintainability. Where volume, latency or a missing connector demand it, we write dedicated code.
We integrate through whatever exists: scheduled CSV/Excel exports, SFTP, database access, email parsing or, where nothing else exists, controlled UI automation — and we tell you clearly how robust each option is.
You do. Source code, workflow definitions, credentials and documentation are handed over; they run in your accounts. Managed support is optional.
Yes. We work with the WhatsApp Business API through approved providers, including template approval and opt-in handling, so your automation is compliant and not at risk of being blocked.
