How to eSign Purchase orders in 3 Steps
Signing purchase orders electronically with BoloSign takes less than 5 minutes. Here is exactly how to do it:
Upload your purchase orders
30 secondsLog into BoloSign and click 'New Document.' Drag and drop your purchase orders PDF — or select it from your files. You can also choose from your saved templates if you have already created one for this document type. The document loads instantly in BoloSign's editor.
Tip: Save this as a reusable template so you never upload purchase orders from scratch again.
Place signature and date fields
1-2 minutesDrag signature fields, date fields, initial fields, and any custom form fields (text, checkbox, dropdown) onto the document where each party needs to sign. Assign each field to the correct recipient role. For purchase orders with multiple signers, set the signing order so each person signs in the right sequence.
Tip: Use the 'Signing Order' feature if your document requires signers to go in a specific sequence.
Enter recipients and send
30 secondsType each signer's name and email address (or phone number for SMS delivery). Add an optional personal message. Click 'Send.' Each recipient receives a secure link to review and sign the purchase orders on any device — phone, tablet, or desktop — in under 2 minutes. No account creation or app download required.
Tip: Use SMS delivery for faster response — 98% open rate vs 20% for email.
After signing
Once all parties sign, BoloSign emails a completed copy to everyone along with a Certificate of Completion showing who signed, when, and from which IP address. The signed purchase orders is stored securely in your BoloSign account and can also auto-save to Google Drive, Dropbox, or OneDrive.
What Paperwork Problems Are Slowing Down Supply Chain Teams Right Now?
Supply Chain organizations waste hours every week chasing signatures, managing document versions, and dealing with compliance gaps caused by paper-based or outdated digital workflows. These are the most common bottlenecks.
Purchase orders sit unsigned for days while deadlines approach
speedWhen purchase orders are sent via email as PDF attachments, recipients need to download, print, sign, scan, and email back. Most people do not complete this workflow on the same day — if they complete it at all. Meanwhile, deadlines approach and the supply chain team spends time sending follow-up emails instead of doing productive work.
No centralized system to track which supplier agreements are signed
visibilityWithout a tracking dashboard, supply chain teams piece together document status from email threads and file folders. The question 'Has this been signed?' should take 2 seconds to answer from a dashboard — not 10 minutes of searching through email chains and shared drives.
Compliance documentation has gaps that auditors find
complianceISO 9001 documentation compliance requires signed acknowledgments, training records, and documented policies. When these are scattered across filing cabinets and email, auditors find gaps. Every gap is a potential finding, fine, or corrective action — and the cost of remediation always exceeds the cost of getting it right the first time.
Per-user e-signature costs scale with your team and do not make sense
costDocuSign charges $25-50 per user per month. A 10-person supply chain team pays $250-500/month for the privilege of sending documents electronically — and hits envelope limits during busy periods. For growing teams, this cost model is unsustainable. Flat-rate unlimited pricing makes more financial sense.
Remote and mobile team members cannot sign paper documents
accessSupply Chain teams increasingly work remotely, travel to client sites, or operate from multiple locations. Paper-based signing requires physical presence. When team members or clients are mobile, the only practical solution is electronic signing that works on any phone, tablet, or laptop from any location.
How Does BoloSign Help Supply Chain Teams Manage Vendor Agreements at Scale?
BoloSign helps supply chain teams eliminate paperwork bottlenecks by replacing manual document signing with instant electronic signatures. Teams create reusable templates for their most common supply chain documents, send them for signing via email or SMS, and track completion in real time through Google Sheets integration — all from one platform starting at $49/month.
Create reusable templates for every supply chain document type
Build your supply chain template library once and reuse forever. Upload your purchase orders, place signature and date fields, save as template, and send to any recipient in 10 seconds. BoloSign supports unlimited templates on the Team plan ($49/mo) — create templates for purchase orders, supplier agreements, quality assurance documents and every other document your team uses regularly.
Send purchase orders for instant mobile signing
Upload your purchase orders PDF, place signature fields, and send via email or SMS. Recipients sign on their phone in under 2 minutes — no app download, no printing, no scanning. BoloSign's mobile-responsive signing works on every iPhone, Android, tablet, and desktop.
Distribute supplier agreements to hundreds of recipients via Bulk Send
Upload a CSV with recipient names and emails, and BoloSign sends personalized supplier agreements to every person in one batch. Each recipient gets their own copy with their specific details pre-filled. Send to 10, 100, or 500 people simultaneously.
Route supply chain documents through the correct approval sequence
Set up signing order so each supply chain document goes through the right approval chain. Signer 1 receives the document first, signs, and it automatically advances to Signer 2, then Signer 3. No one signs out of order, and you see real-time status for every signer.
Track every supply chain document in Google Sheets automatically
Connect BoloSign to Google Sheets so every document event — sent, viewed, signed, declined — creates a new row automatically. Build a free real-time dashboard showing all active supply chain documents and their status. No CRM subscription needed.

What Our Customers Say
“We switched from DocuSign to BoloSign because we were paying $400/month for a 10-person team and hitting envelope limits constantly. BoloSign gives us unlimited purchase orders and supplier agreements for $49/month flat. The templates save us 30+ minutes per day — we set them up once with all the right fields and now anyone on the team can send a perfectly formatted purchase orders in under 10 seconds. The Google Sheets integration was the surprise winner — we built a live document tracker without writing a single line of code.”
Ashley S.
Compliance Officer, Supply Chain, Minneapolis, MN
“What sold me on BoloSign was the Bulk Send feature. During our busy season, we need to send supplier agreements to 50-100 people at once. On our old platform, that meant 100 individual sends with manual data entry each time. Now I upload a CSV and everything goes out in one click — personalized for each recipient. The audit trail has also been critical for our iso 9001 documentation compliance documentation. Auditors love the timestamped records.”
Brian C.
Operations Director, Supply Chain, Austin, TX
“The mobile signing experience is what our clients comment on most. They receive an SMS, tap the link, sign in under 90 seconds, and they are done. No app download, no account creation, no friction. Before BoloSign, getting signatures back on purchase orders took an average of 3 days. Now it is under 4 hours. For $49/month with unlimited everything, it is not even a close comparison to what we were paying before. I wish we had switched sooner.”
