Connect your software to FlipAccounts and FlipERP
A CRM, a hotel or restaurant system, an online store, a payroll tool or your own scripts can post invoices, bills, parties and journal entries into FlipAccounts, and read stock, orders and reports from FlipERP, through the same JSON API the apps use.
How it works
Sign in, open the company, press Details and scroll to API keys. A key is shown once, acts with your permissions, works for that company only, can be read-only, and can be revoked any time.
Send the key as a bearer token to https://platform.flipaccounts.app/api and name the company on each call. JSON in, JSON out. Example below.
Invoices and bills post their journal under the company's tax rules (GST in India, VAT in the Gulf, and so on); posted entries are never edited, only reversed, so your books stay audit-safe.
POST https://platform.flipaccounts.app/api/invoices

Built a product many businesses use?
Hotel systems, billing apps, marketplaces and practice-management tools can add a Connect FlipAccounts button. One click opens a set of books for your customer and returns a key your product uses from then on, so your users get free accounting without leaving your app. Tell us about your product through the contact form (choose "API integration") and we will set up the partner connection with you.
Already on Tally, QuickBooks, FreshBooks or Zoho?
Use FlipERP on its own for stock, orders, production and procurement, and hand the entries to your accounting from FlipERP → Settings → Export your books, as Tally XML vouchers, a journal CSV or Excel, or on a schedule through the API.
Access and pricing
API access is tied to the company's plan. Ask through the contact form and we will tell you what applies to you.
