Cost Analysis

This page compares the cost of running the current platform against the investment required to build and operate SS3.0.

Current Platform Cost#

The platform team has already been right-sized as part of this transition. 2 BAs and 2 QAs have been removed from the original pool.

RoleCountMonthly Cost
Enterprise Architect1$7,779
Application Developers7$44,811
Web Developers12$75,628
Web Designers4$20,006
QA6$28,896
BA3$19,114
AWS & DevOps3$18,062
DBA2$12,224
PM1$7,409
Total39$233,929/mo

Annual run cost: ~$2,807,148/year

These reductions save $22,374/month ($268,493/year) compared to the original 43-person, $256,303/month baseline.


SS3.0 Development Investment#

SS3.0 is built over a 4-month development window using two staffing sources.

Repurposed from the active team#

Six roles shift from maintaining the current platform to building SS3.0. No new cash outlay — cost attribution moves, not the payroll.

RoleMonthly
1× Enterprise Architect$7,779
3× Developers (2 BE + 1 FE)$19,205
1× BA$6,371
1× Infra / DevOps$6,021
Subtotal$39,376/mo

Current platform cost during development: $233,929 − $39,376 = $194,553/mo

New hires#

All remaining SS3.0 roles are filled as new hires. This is the only true incremental cash spend.

RoleMonthly
1× PM$7,409
1× DBA$6,112
2× QA$9,632
3× Developers$19,205
1× UX Engineer~$5,002
1× BA$6,371
1× Infra / DevOps$6,021
Subtotal$59,752/mo

One-time investment: $59,752 × 4 months = ~$239,008


Net Cost During Development#

BaselineDuring SS3.0 build
Current platform (6 repurposed out)$233,929/mo$194,553/mo
New hires$59,752/mo
Monthly total$233,929$254,305
4-month total$935,716$1,017,220

Net incremental spend over 4 months: ~$81,504

The new-hire investment is ~$239K. The net additional burn above the current baseline is ~$82K, because the repurposed 6 are already on payroll.


Post-Launch Savings#

Post-launch team composition is to be defined. The table below illustrates the range of outcomes based on how lean the SS3.0 operating team is.

Team reductionMonthly savingAnnual savingPayback on $239K
15% (~6 roles)~$35,089~$421K~6.8 months
25% (~10 roles)~$58,482~$702K~4.1 months
35% (~14 roles)~$81,875~$983K~2.9 months

Industry benchmarks for modern platform migrations put maintenance headcount reduction at 20–30%, driven by reduced tech debt, automated CI/CD pipelines, and reusable per-store modules.

Savings not captured in the table above:

  • Faster release cycles reduce manual deployment overhead
  • Modular services lower QA effort per change
  • Improved observability reduces incident response time and cost
  • Per-store module reuse reduces onboarding cost for each new store

Summary#

ItemCost
Original annual run cost (43 people)$3,075,636
Revised annual run cost (39 people)$2,807,148
Saving already realised (BA/QA reduction)$268,493/year
SS3.0 new-hire investment (4 months)~$239,008
Net incremental spend above revised baseline~$81,504
Peak monthly during development$254,305
Post-launch annual savingTBD — est. $421K–$983K
Estimated payback periodTBD — est. 3–7 months

The platform has already been trimmed by 4 roles, saving $268K/year. SS3.0 development requires a new-hire investment of ~$239K over 4 months, with a net additional burn of only ~$82K above the current baseline. At a conservative 25% post-launch team reduction, the investment pays back in ~4 months.
