Submit invoices to any AP portal — no API required!
AP portals rarely offer suppliers an API. If your team can log in and submit, so can the agent.
Works on any portal interface
Coupa, SAP Ariba, Tungsten, Jaggaer, Basware or an in-house portal — the agent adapts when layouts change.
No buyer cooperation needed
No integration projects or onboarding queues. Nothing needed from your customer's IT team.
Scales with every new customer
Run submissions in parallel across hundreds of portals, without adding AR headcount.
Your portal credentials stay locked down!
The agent logs in like a team member — under controls your security team can audit.
Encrypted credential vault
Portal logins stay in an encrypted vault and are never exposed to the AI model.
Dedicated service accounts
Least-privilege access per portal, operating inside IP-restricted sessions.
Human-in-the-loop gates
Require sign-off before high-value or high-risk submissions go through.

Success Stories
Ninja Van
Ninja Van issues 10,000 invoices per month to customers with different requirements. Before Peakflo, Ninja Van needs to prepare the invoices manually. Not to mention the effort needed to follow up and resolve disputes. With Peakflo and Netsuite 2-Way-Sync, NinjaVan is able to issue custom invoicing smoother based on specific field mapping. The customer portal also centralizes communication and dispute management with customers.
InMobi
Before Peakflo, InMobi AR team had to create invoices manually with many customizations unique to different regions across the globe. Now, with Peakflo, InMobi can create GST tax invoices with high customization, like HSN/ SAC code, QR code, GSTIN, and e-signatures. Following up on unpaid invoices also made easy with real-time reports.
EverPlate
EverPlate’s operational team, coming from a non-finance background, had a difficult time issuing invoices and tracking payments, resulting in incredibly tight cash flows and wasted man-hours spent doing repetitive tasks. With Peakflo's centralized dashboard, Everplate is able to track invoice status accurately and make customized multi-channel payment reminders
Gazzda
Before Peakflo, Gazzda team had to manually send follow-up emails for 300 invoices per month. Gazzda team also had a hard time doing manual data entry for vendor invoices received by paper and track their status. With Peakflo, Gazzda can automate payment reminders. The scattered vendor invoice management became centralized and the vendor invoice processing has gotten much faster and easier.
Janio
Before Peakflo, Janio didn’t have any visibility into their collections process, making it challenging to plan their budgets. They also need to follow-up manually on 5,000 invoices/month. With Peakflo’s customer status tracking report, Janio is able to see customers’ payment behavior and timeline. The automated reminder workflow also remove the needs to manually follow-up on customer payments.

Pickupp
Before Peakflo, Pickupp had a manual process for collecting and monitoring outstanding payments. This manual approach has led to data silos in communications. With Peakflo easy-to-use interface, monitoring and collecting outstanding payments is very easy. As a result, Pickupp reduced monthly overdue by 40% and DSO by 25%.
EstimateOne
EstimateOne’s three-women financial team had a tough time recording payment status in spreadsheets – which didn’t provide them much visibility on overdue invoices. With Peakflo reports and real-time tracking, EstimateOne was able to gain more insights into customers’ invoice status through the comprehensive reports, making collection much easier and faster.
Glints
Before Peakflo, Glints team had to sent invoice reminders one by one manually from their accounting software. The process of sending and personalizing took around a full day. With Peakflo’s automated workflows, now Glints team automatically sends all the invoice reminders through emails to their customers and reduce DSO.
Aris Infra
ArisInfra’s collections team sent email reminders manually and it took a five-person team to handle all these follow ups. With Peakflo’s automated workflows, now ArisInfra’s finance team automatically sends all the invoice reminders through emails. Now, just one person checks on the automated reminders and tracking customer payments
We Interactive
WE! Interactive, as a Xero accounting software user, needs to send reminders that were sent out one at a time and only through email. With Peakflo’s automated workflows, now We! Interactive accounting team automatically sends all the invoice reminders through email to their customers.
Advance
Before using Peakflo, Advance used Google sheets to send around 500 invoices and send manual email reminders to their customers. It took around half a day every day. With Peakflo automated workflows, now Advance finance team automatically sends all the invoice reminders through emails to their customers and their team is able to focus on more value-added tasks.
Driver Logistics
The Peakflo team was very efficient in understanding our requirements, and they developed customized solutions to make the day-to-day finance operations much more effortless. We’ve been able to reduce our average overdue days by 16 and increase our receivable efficiency by 35%.
Law Firm
In Xero accounting software, the reminders are not supported to have workflows and cannot be sent to specific customer segments in one go. Therefore, the biggest pain point for our client’s finance team was to send all the reminders and follow-ups manually and spend hours on crafting the right messages.
Cove
Before Peakflo, Cove's AR team manually composed payment reminders and chased thousands of tenants monthly with no centralized tracking. With Peakflo's automated multi-channel reminders and self-serve customer portal, Cove saved 2,300+ man-hours monthly and collected 41,469 payments while supporting 2X business growth.
