Sigma Purchase is a comprehensive and flexible purchase ledger system that you can configure to match your own particular method of working. The system can process up to 999 purchase ledgers, each of which can deal with a maximum of 9999 suppliers. Each ledger may operate as a single currency ledger or a dual currency ledger, trading in one currency and accounting in another. In a dual currency ledger you have immediate control over the exchange rates to be used in currency conversions. Most purchase ledger processing is identical for single and dual currency ledgers.
You can use the system to process up to 14 different types of input transaction documents (such as invoices, credit notes, etc.), each having a different set of processing rules.
You may pay suppliers either automatically through the Bacs system or manually. The system prints remittance advices and cheques (if not using Bacs) for automatic payments as required. If you pay manually the system will allocate your payments against invoices.
Sigma Purchase produces a wide range of standard output reports. Some of these are produced automatically at certain points in the processing cycle and others are available on demand. You can choose the sequence in which most of them are printed. Sigma Purchase also offers a report writer which allows you to design the layout of your reports as well as specifying the content.
The Purchase Ledger interfaces with the Sigma Nominal and the Sigma Cash book.
