Frequently asked questions
What is a purchase contract in Flows ERP?
A purchase contract is the main record of one deal with a supplier, with the goods, amounts, terms, receiving schedule, and attachments. Flows creates the payment plan from it, and the amount owed is tracked in the AP write-off center.
How is a purchase contract different from a sales contract?
The only difference is the direction of goods and money: a sales contract brings money in and sends goods out, while a purchase contract does the opposite. Both work the same way, so your team only has one thing to learn.
What is deemed payment?
Deemed payment closes an amount you won't actually pay, such as a price reduction for goods that arrived damaged. The period is settled for that amount with the reason recorded, so your payables stay correct.
Can we receive goods in several batches?
You can receive goods in several batches, following the receiving plan on the contract. Each confirmation, whether partial, in a batch, or via Excel, updates stock in the chosen warehouse and links back to the contract.
Does the payment plan support interest?
Purchase payment plans use the same four options as sales contracts: equal principal, reducing balance, flat rate, or no interest with a credit term. You choose the option on each contract.
Can we import our existing purchase contracts?
You can import them with our Excel templates, which check every row for errors. Your team usually does this during onboarding, then reviews the contracts while running both systems side by side.
