Sync2Books is two separate products. They solve different problems, have different data models, and each has its own dashboard, its own API keys, its own base URL and its own docs. Most of the confusion in these docs in the past came from mixing the two together, so start here.

Accounting API

Write bookkeeping data into an accounting system. Expenses, bills, invoices, and payments — synced to QuickBooks Online, Xero, Sage, Dynamics 365 Business Central, or Odoo.

eTIMS API (Compliance)

Make an invoice legally tax-compliant in Kenya. Register items, issue sales and credit notes, and get a KRA-signed receipt through eTIMS. Has its own API keys and its own docs tab.

​
Side by side

The two use different base URLs, so keep each product’s calls pointed at its own. The Accounting API’s is in Environments & base URLs, and the eTIMS API’s is in the eTIMS API reference.

​
Using both together

A Kenyan business often needs both: you write an invoice through the Accounting API, and the sale is issued through the eTIMS API for a KRA-signed receipt. The two flows are independent — an eTIMS sale doesn’t require an accounting connection, and an accounting invoice doesn’t require eTIMS. Where both are in use, the receipt can be attached to the matching invoice in the connected accounting system.

Still not sure?

  • Building expense reports, bill pay, or invoicing for a business outside Kenya, or that doesn’t need KRA compliance yet? → Accounting API.
  • Your customer is Kenyan and legally required to issue eTIMS-compliant receipts? → eTIMS API. You may still want the Accounting API alongside it if they also want their books synced.
