MSAs, retainers, content approvals and creator contracts, signed
Agency paperwork comes in layers. The master services agreement sets the rules once, a statement of work or retainer sets each month's scope, and the approvals in between decide whether a post goes live. Add influencer contracts, shoot releases and media buys, and it's a lot of chasing. SignMaster sends each layer to the right people and keeps every yes on record.

What an agency gets signed
- MSA and SOWsLegal terms once in the master services agreement, then a statement of work per project with deliverables, dates and fees.
- Retainer agreementMonthly scope, hours, what happens to unused hours, and how either side changes or ends it.
- Media and ad spend authorizationInsertion orders and monthly spend caps, and whether the client pays the platforms directly or through you.
- Content approvalsThe month's posts, ads or emails, approved before they're scheduled. An approval is a record, not a thumbs-up in a chat.
- Influencer agreementsDeliverables, posting dates, usage rights, exclusivity and disclosure. Start from the influencer agreement.
- Shoot releasesModel, photo and location releases signed on set, so the client can use every frame.
Signing a new client
Send the MSA and the first SOW in one envelope. Put the client's marketing lead first to check scope, then whoever signs contracts for them, then yourself to countersign. Set a sign-by date before kickoff, and let automatic reminders follow up so your account lead doesn't have to. If legal wants changes, they can decline with a reason, so you know exactly what to fix before you send a corrected version. On Crew and Company, signing pages and emails carry your agency's logo.

Schedule from the record
When it's approved, everyone gets the sealed PDF. If a post causes trouble later, you know who approved it and when.
Fifty creators, fifty contracts
An influencer campaign means the same agreement with different fees, deliverables and posting dates for each creator. Put a labeled text box in the template for each of those, list the creators in a CSV, and bulk send. Each creator gets their own envelope with their own fee printed in the agreement, and nobody sees anyone else's rate. The results file shows who has signed before the brief goes out.
Disclosure is part of the deal
The FTC expects influencers to disclose a material connection to a brand, such as payment or free product, clearly in the post. Spell out the disclosure you require in the agreement, and have creators initial it.
Signed contracts can flow into your CRM. On Crew and Company, webhooks send each completed envelope as signed JSON, and Zapier's Webhooks by Zapier trigger can pass it on to HubSpot or a sheet.
Pricing for agencies
Account leads, strategists and the producer who sends releases each need a seat. Crew is $49 a month for 5 people, and Company is $99 a month for 15; extra seats are $8 a month. Bulk sends take up to 500 creators at a time on Crew and 1000 on Company. New workspaces get 14 days of Crew free. Compare plans.
What SignMaster doesn't do
- It isn't a proofing tool for comments on each creative. It records the approval.
- It doesn't pay creators or invoice clients.
- It has no built-in CRM connector; HubSpot and similar tools connect through webhooks.
- It emails signing links; copy a link to send it in Slack.
Questions? Answers.
How do I send contracts to many influencers at once?
Make the agreement a template with labeled text boxes for fee, deliverables and dates, then bulk send it from a CSV. Each creator gets their own envelope with their own terms.
Can clients approve a content calendar in SignMaster?
Yes. Send the calendar as a PDF with an Approve field. The client approves or declines with a reason, and you keep the sealed record.
Can signed contracts go into HubSpot?
Yes, through webhooks on Crew and Company. Catch them with Zapier's Webhooks by Zapier trigger and map the fields into HubSpot.
What's the difference between an MSA and a SOW?
The MSA holds the legal terms for the whole relationship. Each SOW describes one project's work, dates and fees under it. See statement of work.
