“We get time card data onto an invoice, reviewed by managers, and out the door to a client in 50% less time than we did previously. We’re getting paid much faster than we were previously and our days sales outstanding dropped nearly six days entirely across the company due to these efficiencies being added.”

Frequently Asked Questions 

What makes managing payments through BigTime different from other systems?

Unlike traditional payment systems, BigTime pulls billing and payment-related data directly from your delivery platform. Invoicing is synced to sales and delivery, so you can see how your entire workflow is functioning and any risks to cash flow. 

This connected workflow means:

  • Less time spent on manual re-entry or jumping between platforms
  • More accurate reports, with invoices already connected to relevant projects
  • Real-time visibility into payment status
  • Faster invoice completion and revenue realization
  • No more invoicing errors caused by porting data from one system to another

What payment methods can our clients use?

Clients can pay via ACH bank transfer and major credit cards (Visa, MasterCard, Discover, AmEx). Each invoice can include a payment link, and clients can also pay in a secure portal where they can view open invoices, schedule payments, and save their information.

What accounting systems does BigTime integrate with?

BigTime integrates with QuickBooks Online, QuickBooks Desktop, Xero, and Sage Intacct. We offer two-way syncs so your team can stop re-entering data and rest assured that financial records are accurate and up-to-date.

Does BigTime support autopay and scheduled payments?

Yes. Firms can give repeat clients the option to opt into autopay for recurring charges. Clients also have the option to schedule one-time payments in the portal, giving them the flexibility to make payments in the way that works for their team.

Thanks to BigTime’s autopay, approval workflows, and payment options, 91% of invoices sent through the platform are paid on time. We are proud to help our customers attain industry-leading invoice completion rates.
