Question

For a customer invoice, the purchase order field is a custom field, is there any plan to make this a standard field?

We use Bigtime for T&M as well as invoicing. However when we sync to QBO we lose the customer purchase order, on the invoice, as purchase order is a customer field and Bigtime cannot map to it.

While BigTime and QuickBooks Online (QBO) integrate seamlessly for Time & Materials billing, their data mapping structures differ. Because BigTime treats the Purchase Order (PO) number as a project-level custom field, standard API integrations cannot automatically translate it into QBO's default invoice fields.

 

As a workaround, you can format your BigTime Project Name, such as Sample Project Name (PO #12345), which pushes the PO number directly into the QBO invoice line details. Alternatively, you can copy the PO number into the Invoice Notes or Memo field during your billing review, allowing QBO to accept it without losing any data.

 

For the most up-to-date information on their feature release timeline, or to submit a formal request to get this standardized, we highly recommend reaching out directly to BigTime Support.
