Agency Onboarding in 90 Days

The contract is signed and everyone feels good. Three weeks later the agency still doesn’t have Google Ads access, the first brief is stuck with legal, and you’ve burned a third of month one paying for people to wait. This is the normal failure, and it’s almost entirely preventable with a week one checklist and three written gates.

Onboarding is the most influential period of the whole relationship. What you transfer in the first fifteen working days sets the ceiling on everything that follows, because an agency that never understands your buyer will produce competent work aimed at the wrong person for a year.

What has to happen in week one

Week one is access and context. Nothing else. If you finish week one with credentials working and a kickoff done, the agency can start producing in week two instead of week five.

Start access requests before the contract is countersigned. At most SaaS companies with a real security function, adding an external vendor to Google Ads or a CRM triggers a review that takes eight to fifteen business days, and nobody plans for it. If you’ve already run the security and privacy review for marketing tools on similar vendors, reuse that paperwork.

Here is the access list that covers about 95 percent of SaaS engagements:

The asset handover list nobody sends

Assets are where you buy back agency hours. Every document you don’t hand over is a document the agency reconstructs badly at your expense.

Send these before kickoff: the current ICP definition, win/loss notes from the last two quarters, ten recorded sales calls (Gong or Chorus links are fine), the pricing page history, the objection handling doc sales actually uses, brand guidelines, a list of approved customer logos and case studies, past campaign results including the failures, and the analytics annotation history so the agency knows why traffic fell off a cliff last November.

Add product context that marketing usually forgets: the integration list, the security and compliance page, current SOC 2 status, and any product data the agency will need for programmatic or comparison pages. Missing product data is the quiet killer of comparison content programs, because the agency writes the page, legal flags an unverifiable claim, and the page sits in draft for two months.

A kickoff agenda that transfers context, not brand history

Ninety minutes, one meeting, six blocks. Skip the company history deck. The agency is not going to sell your product, it’s going to reach people who might buy it, and those people need the same things your sales team needs.

Everything else goes in a pre-read. If you need help structuring what to send, the SaaS agency brief template covers the written half of this.

Deliverable gates at day 30, 60 and 90

Gates are the mechanism that lets you fire early without drama. Agree them before signing, write them into the ramp plan, and review them on the calendar day rather than whenever someone remembers.

The gates differ by service line, because an SEO engagement and a paid engagement produce evidence at different speeds. Here’s what reasonable looks like:

Service line	Day 30 gate	Day 60 gate	Day 90 gate
SEO and content	Audit delivered, keyword map approved, 3 briefs written	6 to 10 pages published, internal linking fixed, technical issues closed	First ranking movement on 5+ terms, 2 pages in top 20
Paid acquisition	Tracking verified, account restructured, first 2 campaigns live	First CPL read on 200+ clicks per campaign, 2 creative iterations	CPL trending toward target or a written case for why not
Lifecycle and email	Data audit, 3 flows mapped, deliverability baseline	2 flows live with holdout groups	Open and reply lift vs holdout, one flow at statistical read
Demand gen full stack	Tracking, ICP doc, channel plan with budget split	2 channels live, MQL definition agreed with sales	Pipeline attributed in CRM, cost per opportunity baselined
Product marketing	Messaging audit, 5 customer interviews booked	Positioning doc approved, one page rewritten	Sales adoption of new messaging measurable in 3+ decks or calls

I’ll take a position here. Any agency that cannot ship something measurable within 45 days is either under resourced on your account or blocked by something on your side, and it’s your job to establish which by day 30 rather than discovering it at renewal. The diagnostic is simple: ask the account lead to list every open blocker with the name of the person who owns it. If the list is all your people, fix your side. If the list is empty and nothing has shipped, the problem is resourcing. This is also the sharpest reason to ask about team structure during agency vetting, because senior pitch teams handing off to junior delivery teams is where the 45 day rule usually breaks.

Leading indicators to watch before results appear

Results take a quarter minimum. Leading indicators take two weeks, and they predict the quarter accurately enough to act on.

Watch these weekly:

• Briefs approved on the first review versus sent back (target: 70 percent or better first pass by week six)
• SME interviews booked and held (target: two per month, and this is your obligation as much as theirs)
• Days from draft delivered to published (target: under seven, and this metric is nearly always about you)
• Tracked conversion path verified end to end, including CRM field population
• Account lead turnover (one change in 90 days is a yellow flag, two is red)
• Meeting-to-work ratio in the agency’s own time reporting

Two of those are really measuring you. Approval speed and SME access are client-side inputs, and when they’re broken the agency’s output quality collapses regardless of talent. That’s the honest tradeoff of agency work: you’re buying execution capacity, and execution capacity needs a steady supply of internal context that someone on your team has to produce.

The risk register: five blockers that appear in almost every engagement

Write these into the ramp plan on day one with an owner and a date. They show up in roughly the same order every time.

Sequence matters. Tracking must close before paid scales, or you spend three months optimising to a number that isn’t real.

The day 90 decision: renew, extend or cut

Make this decision on a scheduled date with the gate doc open. Most companies drift into renewal because the conversation is uncomfortable, which is how a bad engagement reaches month nine.

Three outcomes, and clear evidence for each:

Renew when two of three gates were met on time, leading indicators moved, and the agency can name specifically what it will do next quarter with a number attached. Renew at the same scope for one more quarter before increasing spend. Increasing spend at day 90 is almost always premature.

Extend the ramp when gates were missed for reasons on your side. Be honest here. If your approvals ran at nine days and you never booked an SME, the agency did not get a fair 90 days. Extend by six weeks, fix your inputs, and re-gate. Do this once, never twice.

Cut when gates were missed for reasons inside the agency’s control, the account lead has changed twice, or the work reads like it could be for any company in your category. That last test is the most reliable one I know. Take three pieces of delivered work, remove your logo and product name, and ask whether it could belong to a competitor. If yes, you’re paying retainer rates for template output, and a specialist agency or a different model entirely will serve you better.

Cutting has real costs: 30 to 60 days of notice in most contracts, a fresh ramp with whoever comes next, and the internal credibility hit of having chosen wrong. Run the numbers before you switch. The agency versus in house cost calculator is worth ten minutes here, and if the answer is that you needed strategic direction rather than execution volume, look at agency versus fractional CMO instead of shopping for another agency.

We renewed twice on vibes and cut on month eleven. The gate doc would have told us in month three.

What to do this week

If you’ve just signed, do three things today: send the access request list to IT, book the kickoff with the six-block agenda, and write the three gates into a shared doc that both sides can see. If you’re mid-engagement and nothing above is in place, you can still retrofit gates at the next monthly review, and the agency will usually welcome it because clear targets protect them too.

For the wider context on picking and managing agencies, start at the SaaS marketing agencies hub. If you’ve just joined the company as well as the agency, run this alongside the first 90 days as a SaaS marketing lead checklist, and if your product has an onboarding problem of its own, the same gate thinking applies to customer onboarding marketing.
