At your scale, the buy-vs-build line moved — most teams haven't noticed. We audit your stack ($2,500, 5 days) and rebuild the lines that stopped paying back on direct enterprise billing with AWS · OpenAI · Anthropic · Stripe · Postmark · Cloudflare · Twilio. You keep the wrapper margin (the markup you currently pay your SaaS layer). You own the code.
~$360K already paid in wrapper margin (typical 18-month tenure on Jasper before audit).
A senior engineer runs The Upstream Method™ across your stack — five phases, five days, ~40 senior-engineer hours. You walk away with a 30-page report and an action list — even if you never hire us for the build.
No off-shore juniors. No PowerPoint deck handed to a fresh associate. The same principal engineer who wrote the methodology runs your audit.
Methodology refined across a body of stack audits since 2024. Same five phases, same deliverables, every engagement.
Four categories where the wrapper margin is biggest. The underlying primitive · what direct billing actually costs · what we'd build to give you the UI back.
Jasper · Writer · Copy.ai · Jenni
— wrappers of OpenAI · Anthropic API
Mailchimp · Klaviyo · Omnisend
— wrappers of AWS SES · Postmark · Resend
Cloudinary · ImageKit · Bunny resellers
— wrappers of S3 + CloudFront · Cloudflare R2
Algolia · Typesense Cloud · Elastic Cloud
— wrappers of Meilisearch · OpenSearch · direct enterprise
Numbers reflect typical Series A / scale-up volume. Actual numbers from your audit may vary — that's the audit's job.
A $14K rebuild in 2–3 weeks, next to an $80K agency quote and a 6-month internal build, looks impossible. It isn't. Three things compound.
Senior engineers (12+ years) using AI as a force multiplier — not the primary author. AI doesn't get tired at 2am, doesn't skip the boring tests, doesn't drift from the design system. Same patterns across every codebase. Same code-review standard. You get fewer bugs and predictable architecture — not faster slop.
250+ products delivered across 15 years. Your Klaviyo replacement isn't being invented — we've shipped 9 of them. Your Datadog self-host isn't a research project — it's a deploy script we've run before. Domain knowledge is a sunk cost we already paid. The productivity dividend is yours.
It's from the SaaS layer above us. AWS · Anthropic · OpenAI · Stripe · Twilio · Postmark — billed direct to your accounts, not ours. You keep the wrapper margin the SaaS vendor used to keep. We don't take a cut of infrastructure spend. Ever.
No offshore juniors · no LLM-only output · no hidden hourly rates that 3× after engagement. The senior engineer reviewing your PRs is the same one who scoped your build.
Illustrative profiles based on published wrapper-vs-direct rate cards and team-sizes we typically work with. Your audit produces the exact numbers for your stack — start with the $2,500 audit and we put real receipts on the table.
Indicative range: $50K–$200K Y1 saving at this stack scale · figures derived from public wrapper rate cards vs. direct-billing pricing · your audit returns numbers specific to your stack.
If you're in the right column, the audit pays for itself in week 1. We turn away ~30% of inbound to keep this honest. Book it — or email us first if you're unsure.
No email gate. Live updates. Honest numbers — including ours.
SaaS prices reflect typical SMB plans (5–10 seats where applicable). Build estimates rounded to the nearest bundle tier. Real quote depends on scope.
Six pre-priced bundles for the most common SaaS stacks. Each ships in 2–8 weeks, fixed price, your code, your servers, your direct-billing accounts.
Replace Notion / Airtable / Confluence with a custom workspace tuned to how your team actually works. Multi-user, RBAC, full-text search.
Custom email automation on Postmark/SES + social scheduler + landing-page builder. Unlimited contacts, no per-message price hikes.
Direct Claude / GPT API + custom UI for content, briefs, summaries. Same UX as Jasper/Writer at ~10% of the cost. Your prompts, your data.
Replace Retool / Airtable / Linear (where it fits) with admin UIs and dashboards built around your actual data and workflow.
Sentry + PostHog + n8n self-hosted on your VPS, configured + integrated with your app. Same tools, no per-event pricing.
Tell us what you pay for. We'll quote a fixed-price replacement covering only what's worth it. Honest scope, no upsell.
The savings are real. The reasons to own go deeper.
Notion +25% in 2024. Salesforce +9% in 2025. Adobe +20% on Acrobat. Your build doesn't get re-priced annually.
Exports become unusable when SaaS pivots. Your custom build's database is yours. Forever. Including the schema.
SaaS picks the 80% of features 80% of users want. The 20% you actually need? Build it once, use forever.
Your custom internal tool can become a productised SaaS sold to your peers. A subscription can't.
Honest answer: only if you skip a maintenance model. Three options. Most clients pick option 2 + their own engineer.
Your team owns it. Runbook + architecture doc + 1-hr handover call. Standard stack — any senior engineer onboards in a week.
When it fits: you have (or plan) an in-house engineer.
12 hrs/mo from the same engineers who built it. Patches · deps · small features. 24h P1 SLA · 1h critical. Cancel any month.
When it fits: predictability without hiring. Most ICPs land here.
40+ hrs/mo. Fractional engineering team for the product line. Roadmap, features, monitoring, alerts.
When it fits: mission-critical build, no hire planned.
Code is in your GitHub. Standard stack — any senior engineer takes over in a week. Runbook + architecture doc travel with the repo.
SaaS lock-in is also maintenance debt — just hidden. Notion pivots, Klaviyo raises 25%, Cloudinary gets acquired — you migrate on their timeline. With custom code, you migrate on yours.
$2K/mo light retainer breaks even when monthly SaaS savings exceed $2K. ICPs at $5K+/mo clear this comfortably; sub-$5K stacks don't — the audit ICP qualifier filters for it.
$6K+/mo embedded works when build is mission-critical and savings $10K+/mo. Available — rarely needed.
A fair question. The wrapper-margin thesis is replicable. What's not easily replicable is the pattern library, the provider relationships, and the operating discipline behind delivering on it. Four answers.
Established accounts and direct working relationships with AWS · OpenAI · Anthropic · Stripe · Postmark · Cloudflare · Twilio. Your build deploys on enterprise-tier billing day one — terms a new agency would need 6+ months and 5× your volume to access independently. That's most of the wrapper margin you're recapturing.
We know which SaaS are wrappers, which APIs are commodified, which providers issue contracts under $50K/yr revenue. A new agency learns this on your audit. Same scope from a fresh shop costs 2–3× and misses half the savings.
Most agencies disappear at handover. Allied BizTech's $2K/mo retainer is the same engineers who built your stack. No re-onboarding cost — critical fixes ship in hours, not days. Build + maintenance with one team means paying once for context, not twice.
Live, named products: Bestinform.eu · Rexera · CitizenTestPrep · HIPAA wound-care app for 100+ providers. Verify: D-U-N-S 86-431-9607 · CIN U72900TN2009PTC072281. Reference-check the case studies. A solo dev or new agency can't show this — not yet.
If you do the audit DIY or with another agency and find a cheaper path that genuinely delivers the same — take it. We turn away ~30% of inbound for fit reasons; we're not the only option in this category, just the one with the longest receipt and the strongest provider relationships. The thesis is yours to keep regardless.
