This is a complete list of all API calls that provide "reports" — or any aggregated data, in one form or another.
Produces a "Sales report" (which, in addition to net sales, also reports VAT or sales tax) or a "Cost of Goods Sold" report (which reports costs and sales margins). Offers many different aggregation options.
Returns all customers who have any unpaid invoices (or prepayments, or store credit), and their current balance.
Same as previous — but additionally, for each customer, returns a link to a payment reminder letter (PDF), and links to all unpaid invoices (PDF).
Returns the cost of each sold item in the specified time period. The same information can be retrieved from API call getSalesReport, too.
Returns a list of sales documents to which tax exemption has been applied. (For more specific use cases.)
Returns a list of invoices to which rounding has been applied. (For more specific use cases.)
Returns current inventory quantities on hand (at the moment, or on a specific date), reserved quantities, weighted average cost, Reorder Points and Restock Levels.
Returns total value of inventory by location, on a specific date.
Returns the quantities that have already been ordered from suppliers (but have not been delivered yet). When deciding on how much to reorder, the already-ordered quantities must be factored in to prevent double ordering.
Returns only a list of reserved product quantities (ie. all products that have been reserved with a Sales Order, Prepayment Invoice, or a Sales Quote). The same information is also available from API call "getProductStock", but a standalone call may be sometimes more efficient (less output to process).
For a specific use case: if an application wants to synchronize the total inventory quantity across all locations. Use it if your application only stores a total inventory quantity for each product (not separate quantities per store), and wants to stay up-to-date with all changes made in Erply.
Returns sales orders that can be fulfilled with the current quantity in stock. (The report arranges unfulfilled sales orders in chronological order, starting with the oldest, and prints out those for which it can allocate inventory.)
For the "day closing" procedure. Returns the total of all sales transactions taken place during the cashier's shift, grouped by payment method.
Returns an "X Report" or "Z Report".
Returns all recurring billings and the "billed until" date for each one. This is necessary for deciding which customers need to be issued a new (monthly, yearly) bill — and what period must it cover.
