# Supplier & Vendor Follow-Up: done-for-you AI automation by BufferSol

> A done-for-you supplier follow-up automation is an AI agent that tracks every open purchase order line, emails suppliers for acknowledgements and ship dates, reads their replies and PDF confirmations, and updates promised dates in your ERP. It spots price, quantity or date changes, warns buyers about orders that will land late, and escalates suppliers who go quiet. BufferSol builds and runs it in your mail and ERP, live in 3 to 6 weeks.

## Every open PO confirmed, chased and dated without inbox hunting

**Who it is for:** Procurement and purchasing teams at manufacturers, distributors and retailers that place hundreds of POs a month with suppliers who confirm by email, PDF or phone rather than EDI.

### Signs you need it
- Buyers keep a spreadsheet of which suppliers have confirmed and which have not.
- Promised dates in the ERP are blank or out of date, so planning works from guesses.
- You find out a shipment is late when the production line or customer asks where it is.
- Suppliers change price or quantity in their confirmation and nobody notices until the invoice arrives.
- Smaller suppliers will not use your supplier portal.

## Business outcomes
- **Real promised dates in the ERP.** Confirmed ship and delivery dates are written back to each PO line, so planners and customer service work from facts.
- **Early warning on late supply.** Lines at risk are flagged while there is still time to expedite, split or source elsewhere.
- **Changes caught before invoicing.** Price, quantity and date differences in supplier confirmations are surfaced to the buyer instead of surprising AP later.

## How it works today
1. A buyer sends a PO from the ERP and waits for the supplier to confirm.
2. They check their inbox and a tracking spreadsheet to see who has replied.
3. They send reminder emails and leave voicemails for suppliers who have not.
4. When a confirmation arrives, they read the PDF and type the promised date into the PO line.
5. Near the due date they chase again for ship dates and tracking, and pass bad news to planning by email.

Hidden costs:
- Buyer days spent on reminders instead of sourcing, negotiation and supplier risk.
- Production stoppages, expedite freight and missed customer dates from late surprises.
- Overpayments and disputes when supplier changes slip through to invoice matching.

## How it works done for you
1. When a PO is released, the agent records each line and its required date, and sends the supplier a clear request to confirm.
2. It follows up on a schedule you set, by supplier tier, and changes tone and channel when replies do not come.
3. It reads supplier emails and attached confirmations, extracts promised dates, prices and quantities, and matches them to PO lines.
4. It writes confirmed dates back to the ERP and flags any difference in price, quantity, item or date for the buyer to accept or reject.
5. Before each due date it asks for ship confirmation and tracking, and checks carrier tracking where available.
6. It alerts planners in Teams or Slack about lines at risk, with the supplier's latest reply attached, and suggests options.
7. Each message, reply and ERP change is logged by PO line, building a supplier on-time and responsiveness record.

## What changes for the team
- **Buyer.** Today: Chases confirmations by email and phone and types dates into PO lines. Done for you: Handles the suppliers and lines the agent escalates and works on sourcing.
- **Production or demand planner.** Today: Plans around missing or stale promised dates. Done for you: Gets early alerts on late lines with the supplier's own words attached.
- **Procurement manager.** Today: Has no reliable data on which suppliers confirm on time. Done for you: Reviews supplier responsiveness and on-time scores built from the logs.

## KPIs we measure
- **PO acknowledgement rate:** Share of new PO lines confirmed by the supplier within your target window, baselined from current ERP data.
- **Lines with a current promised date:** Open lines with a supplier-confirmed date, checked weekly.
- **Late lines found early:** Lines flagged late at least a set number of days before the required date, versus lines found late on the day.
- **Expedite freight spend:** Premium freight caused by late supply, tracked monthly against the prior year.
- **Confirmation discrepancies caught:** Price, quantity and date changes flagged before receipt or invoice.

## Industry data
- 73%: of organizations suffered supplier disruptions in the past 12 months (survey of 200 CPOs and CSCOs in the US and UK, 2025) ([Sphera](https://sphera.com/wp-content/uploads/2025/10/sphera_survey_report_ai_powered_supplier_risk_management_final.pdf))

## Systems it connects to
SAP S/4HANA, SAP Business One, NetSuite, Microsoft Dynamics 365 Business Central, Acumatica, Microsoft Outlook, Gmail, Microsoft Teams, Slack, project44

## Guardrails
- The agent can update promised dates, but any change to price, quantity or item needs a buyer to accept it.
- Messages to suppliers use approved templates and your buyers' sending rules, with escalation steps you define.
- Strategic suppliers can be set to draft-only, so a buyer sends every message.
- Every supplier message, reply and ERP update is logged against the PO line.
- The agent has read and limited write access in the ERP, scoped to purchasing fields.

## What teams say about this work
- Smaller suppliers often cannot send order confirmations by EDI, so they confirm on paper or by email and the buyer has to key the data into SAP by hand. ([SERKEM](https://serkem.de/bsk-pdf-manager/sap-supplier-backflush))
- Many buying teams still chase acknowledgements with emails, spreadsheets, phone calls and voicemails, checking inboxes again and again for promise dates. ([SourceDay](https://sourceday.com/blog/automate-supplier-follow-up/))
- Supplier-side reviewers of SAP Ariba complain about fees, duplicate accounts and extra work for small suppliers, one reason many vendors avoid buyer portals and keep replying by email. ([Capterra](https://www.capterra.com/p/227334/SAP-Ariba/reviews/))

## Frequently asked questions
### How quickly can this be live?
Usually 3 to 6 weeks. We connect to your ERP and the buyers' mailboxes, agree follow-up rules by supplier tier, and load your message templates. The agent then runs in draft mode so buyers can see what it would send. Once they are comfortable, it starts sending and updating dates on its own within the limits you set.

### What does it cost?
We do not publish pricing because it depends on PO volume, the number of suppliers and mailboxes, and your ERP. Cost is quoted after a short scoping call where we look at a sample of open POs and supplier replies. You receive a fixed scope and quote before we begin the build.

### Will suppliers know they are talking to an AI agent?
That is your choice. Most clients send from a shared purchasing address with the buyer copied and a short note that the message is automated. Replies go to the same thread, so a buyer can step in at any point. Suppliers do not need to log into anything new.

### Can it read supplier confirmations in different formats?
Yes. It reads email text, PDF order acknowledgements, spreadsheets and scanned documents, in English and other common European languages. When a document is unclear or the line match is uncertain, it asks the buyer rather than guessing, and it learns each supplier's layout over time.

### Does it replace a supplier portal or EDI?
No. If you already get EDI acknowledgements or use a portal, the agent reads those too. It covers the large group of suppliers who will only ever reply by email, so you get one complete view of every open line regardless of how each supplier communicates.
