How do you get Big Banks to integrate your SaaS products fast enough?

You love them, but you need them to get live, a primer on wrangling slow customers

Signing big customers is hard enough, but it’s only half the battle. There’s an adage in fintech startups - banks can take longer than you can stay solvent. Especially in the current market. I’ve built SaaS products that could take one customer just weeks to go live with, and another customer literally 18 months from signing. Expecting regular project meetings, integration support from you all along the way. 

When a big customer lags on going live, it’s not just lost revenue opportunity. It’s also likely a significant cost in distraction and resources supporting that customer in their integration project. Resources that could have been better spent in getting after the next customer and the one after that.

Here’s a few of the recommendations I’ve provided to my own advisory clients and portfolio companies when they (inevitably) encounter problems with customer integration delays.

Pricing Strategy Sticks and Carrots

The goal here is both to create a better sense of urgency, and practical deadlines for your customers. But also to help you de-risk when you can start seeing, at least some, recurring revenue from each new deal. A key insight here is that most customers don’t think their project is going to be the one that goes off the rails and gets delayed, so some of these are easier to negotiate into contracts than you might think.

Start your recurring billing clock at time of signing. Make sure you have a component of your billing (a minimum volume, a monthly/annual license fee) that is recurring, not tied to volume, and that starts either immediately at signing, or within a fixed time from date of signing. 

Charge for integration support. Set a modest but reasonable integration fee. You may waive it, particularly for first-mover customers, but set the value of integration support in the minds of your customer. But then also make it a metered or recurring fee.

Cap integration support. Don’t let difficult customers drain your resources indefinitely. Whether you waive it initially or not, set an expectation that your team will provide a fixed amount (in hours, or for 30 days etc.) of support. If the customer needs more than that (intentionally or otherwise) then let them pay for incremental cycles of support. 

It’s not just about the one-time integration. Set expectations in your contracts clients will have to keep up with your future versions, including any reasonable level of retesting or reintegration over time. You can also build in provisions for ‘extended support’ where your service fees escalate in price if clients can’t keep up with some minimum reasonable upgrade cadence. 

Pricing incentives. Helpful  for unproven early stage products or network-value products. Provide pricing incentives for customers going live early, for participating in beta testing but also contingent on going live.

Air Cover

Arm your champions inside the customer’s organization. Think of your job as to make your main champions inside the customer look like geniuses to their peers and get them promoted. 

Do the customer’s job for them. Give them fill-in the blanks business and ROI models. Sample project plans. Sample test plans. I used to always build a mock bank app (see dogfooding) both as a test harness, UX testing tool and demo my own SaaS products, but ALSO as a reference implementation to share with customers

Support all the stakeholders. This one should have started early in the sales cycle. But it means having resources to help your customer team talk to legal, security, regulatory, ops, finance etc. There will be common questions/concerns everyone has, arm your champions with ready-to-go tools, collateral and answers.

Don’t forget the product as soon as it’s launched. Make sure they don’t forget to actually communicate, promote and actually use this fancy product they just worked so hard to buy and integrate from you (I’ve seen it happen). Help them with marketing, communication examples and templates, post-launch best practices to drive usage, metrics and reporting to provide feedback.  Put marketing clauses and potentially associated budget expectations in contract. As well as your ability to publicize the work/case study it.

Sometimes the contract can wait. When it’s not the technical integration but the commercials/legal, don’t let client legal be a blocking factor. You can start integration without final paper. It’s not the best practice but I’ve actually gotten major banks live in prod with an integrated product before all the final contractual and redlines were sorted out. Which means it can be done!

Design, Dogfood and iterate your Integration Experience

Clean API design. This means following and not breaking (without good reason) standard patterns like Restful API and well formed JSON. Be consistent. Try to make your APIs, data types and validation standards feel like they came from the same author and engineering philosophy. Conway’s law will creep up on you, but try not to make understanding your own organizational structure and history not your customer’s problem.  

Developer Friendly Sandboxes. Inline your sandbox with your developer documentation. Allow developers to test and learn api behaviour within the online docs themselves. Provide samples across multiple common languages/frameworks. Try to deploy all your products to shared sandboxes to better enable developers to test and experiment with creative solutions, potentially composed of multiple products/apis. 

Dogfood and iterate on your integration patterns. Build a mock customer app and integrate your service to it. Document your experience doing that. I’ve gone so far as to hire a third party shop to attempt to integrate an early version of your product, only using your first draft documentation. You will learn a LOT from that experience. 

Use generative AI. It’s actually pretty easy to train/embed an LLM on your product and integration documentation. Use that to help you more quickly spin up integration collateral, even highly customised for specific customers and usecases. Use that as an internal tool/refference, or just expose that LLM directly to customers as part of your toolset. GenAI can also be quite useful for generating synthetic test data. If done well, synthetic data helps to solve for privacy, security and compliance problems of how to test against realistic production data - without actually using real data.

Keep as much server-side as you can. Generally, the fewer the lines of code, data or logic the client has to own the better. Lower surface area means, less to build, less that can break, is easier to secure, version control and maintain later. For SDKs in particular, what’s the bare minimum of static code that needs to live client side or as native-ap code vs code can be loaded dynamically at runtime? You can update and improve your server side code continuously, with a big enterprise client, you might be lucky to get them to come back and upgrade your integration more than annually. 

Do the customer’s UX research for them. I’ve mocked up a big banks mobile app and UX tested and optimised the user experience with 3rd party research reports to back it up. Double bonus here, saves your customers time, and mitigates risk of big banks over-complicating or just mucking-up the end-user UX (which you just know they are wont to do)

Pave the elephant paths. For better or worse, your first integrations tend to be all hands on deck affairs. Engineering, product tend to be deeply involved. Bugs are found, key assumptions have to be corrected, gaps in documentation needs to be sorted out, new onboarding processes invented as you go. But your goal should be to make each new customer smoother than the last. Hopefully after just a few, you are handing over a repeatable playbook over to dedicated (and more scalable) support teams.  Make your integration machine continuously better, faster and lighter with each new customer. Track KPIs on integration speed and resources consumed to know if you are making progress.
