Do we need to buy any software?

No. No software, no integrations, no licences. The work happens in your existing sheets and exports.

Why is the media plan involved in inventory planning?

Because it is the only forward looking demand signal the business owns. Sales history tells you what happened. The media plan tells you what is about to happen.

Spend to Stock

We plan your inventory off your media plan, not last quarter's sales.

Q: Why are there no client names on this page?

The companies we work with do not issue public testimonials. Reference calls are available at proposal stage, once the conversation is serious.

Q: What if our data is a mess?

It usually is. The Cash Scan is designed to work with exports rather than a clean data warehouse. If the data genuinely cannot support the work, we say so in the first call and you pay nothing.

Spend to Stock turns your channel budgets and launch calendar into unit level buy plans. Findings in 7 days. A working system in 28. Two calls a week from your side.

15 years in eCommerce operations, from 300 to 4,000+ orders a day.

Spend to Stock Model

Week	Media	Units needed

W37	Baseline	1,910
W38	Launch	4,260
W39	Launch	3,980
W40	Baseline	2,100

Illustrative structure. Your version is built from your channel budgets, launch dates and historical cost per acquisition, with the date each SKU class has to be ordered.

Your next purchase order is being decided by last quarter's sales.

Your next quarter's demand is being decided by a media plan your ops team has never seen.

Marketing knows what is coming six weeks out. Budget by channel, launch dates, the promo calendar. Procurement plans from what already happened. Nobody translates between the two.

That gap is where stockouts on your best campaigns come from. Not from bad forecasting. From forecasting that was never shown the plan.

Ask your ops lead what next month's media budget is. If they cannot answer, that is your forecasting problem, and no tool on the market fixes it.

What most brands try first, and why it does not hold

Buy a planning tool. It executes rules. Most companies never wrote the rules, so the tool sits half configured by month three.
Hire a demand planner. Good move, wrong order. Without a written system they inherit a spreadsheet only one person understands.
Ask the 3PL. They optimise storage and shipping. They do not decide what you buy or when.
Live with it. This works until growth makes it expensive, and it gets worse in exactly the quarters that matter most.

Paid social sells discovery SKUs. Search sells replenishment SKUs. Move budget between them and the buy plan is wrong before the PO goes out.

The mechanism

Spend to Stock

Three steps. Nothing new to install.

Read the plan

Channel budgets, launch dates, promo calendar, and historical cost per acquisition by channel. The information already exists. It has just never reached the person writing purchase orders.

Translate to units

Planned spend becomes expected units by SKU class by week, with the date each class has to be ordered in order to arrive in time. This is the page that goes to your CFO.

Write the rules

Reorder points and safety stock that move when the media calendar moves, written into the sheets your team already uses. When a campaign goes live, the trigger moves on its own.

Works with the data you already have. Shopify, WooCommerce and Amazon Seller Central exports, plus a read only view of your ad accounts or a simple spend by channel export. No new software, no data migration, no IT ticket.

You already have a planning tool

Good. It will work better. Planning software executes rules, and this is what writes them. We do not replace it, and we do not ask you to install anything else.

Media budgets change every week. Inventory arrives on a ten week lead time. No forecasting algorithm closes a gap that wide. A shared calendar does.

Step one

The Cash Scan

Seven days. Four documents. You see the numbers before you commit to anything.

What you get

Cash Map. One page showing where working capital is sitting, by SKU class.
Availability Gap Report. Which SKUs are costing you sales, and what it adds up to.
Spend to Stock Model. Your planned media budget translated into required units by week, with the point where lead time stops being able to catch up.
30/60/90 plan. Named owners, in order, with the media calendar built in.

What we need from you

One 60 minute call
A sales and inventory export
A read only view of the ad account, or a spend by channel by week export

That is the whole ask. Total time from your side in week one is about 90 minutes.

The Cash Scan

$1,500

Seven days from kickoff to handover call.

Credited in full

If you move to the Sprint within 30 days, the $1,500 comes off in full. So the decision in front of you is not $8,500. It is whether you want to see the numbers first.

The guarantee

Findings in seven days, or you do not pay.

Show me where my cash is stuck

Two calls. No software to install.

Step two

The 28 Day Availability Sprint

From $8,500. Each phase has a number attached to it, so you know on any given day whether it is working.

Days 1 to 7

Stabilize

Your top 20 SKUs get a reorder point and safety stock that read the media calendar. When a campaign goes live, the trigger moves on its own.

Target: top 20 SKUs covered

Days 8 to 21

Systematize

The weekly ordering rhythm runs without you. One person executes it, start to finish, in 90 minutes.

Target: 90 minutes, one owner

Days 22 to 28

Prove

Availability and coverage measured before and after, on one page you can forward without explaining it.

Target: measured, on one page

What you keep

The reorder system, inside your own sheets
A supplier scorecard
The Reorder Rulebook. The document you hand a new planner on day one
A recorded handover
30 days of async support after we finish

What it costs you in time

Two calls a week, thirty minutes each.

Capacity

Two Sprints a month. That is how many one person can run properly.

The guarantee

Installed and handed over in 28 days, or we keep working at no charge until it is.

A launch that goes well is the most expensive thing that can happen to a supply chain that was not told about it.

What else you could do with the same problem

Option	Time to result	Risk
Do nothing	None	Stockouts and dead capital every month. The problem grows with the business.
Hire a demand planner	3 to 6 months to productive	No system to hand them. They inherit a spreadsheet one person understands.
Buy planning software	8 to 12 weeks	Needs clean master data and defined lead times that most companies do not have yet.
Larger consultancy	8 to 12 weeks to first finding	Junior delivery team. A deck at the end.
Supplynaut	7 days to findings, 28 to a system	Scan first. You see the numbers before you commit.

Hire the planner anyway

Just hire them into a system rather than into a spreadsheet only one person understands. The Sprint builds the thing you hand them on day one.

Proof

Client names are withheld. These are companies that do not do public case studies, which is probably true of yours as well. Reference calls are available at proposal stage.

CASE 01

Baby products, DTC

Scaled from a few hundred orders a day to over 4,000 across engagements, in a category where shelf life and stockout risk pull against each other on the same SKU.

CASE 02

Q-commerce, large assortment

Availability across a wide digital assortment and hundreds of suppliers, with a weekly ordering rhythm one person could execute.

CASE 03

New location, 6,000 SKUs

Initial inventory build for a location with no sales history. Not a forecasting problem. A shelf space allocation problem wearing a forecasting costume.

Built and running in production

Supplier Delivery Accuracy Agent

Compares promised against actual delivery, supplier by supplier, and flags drift before it reaches the shelf. Removed 60 to 80 hours of manual checking a month in production.

Shelf Life Compliance Agent

Watches remaining shelf life against sell through rate and flags the units that will expire before they sell. Reduced shrink by about 20 percent in the affected flow.

Supplier lead time is not a number. It is a distribution. The number in your ERP is usually the best case they quoted once, in a quarter when nothing went wrong.

Who is behind this

Supplynaut is a small practice, not an agency.

Strahinja Jovanović has spent 15 years in eCommerce and retail operations, at every size from 300 orders a day to over 4,000. Sourcing across China, Vietnam, Thailand, Mexico and the EU.

Specialists join per engagement, chosen for what that engagement actually needs. You always deal with the person doing the work.

The same pattern, fifteen years, at every size. That is the point. Nobody recognises a pattern until they have seen it forty times.

This is not for you if

You are under $2M in revenue. The system costs more than it returns at that size.
You do not run meaningful paid media. The model needs a plan to read.
You want someone to run inventory for you. That is the retainer, and it comes after.
You want to implement new software. We work inside what you already have.
You cannot give two calls a week for 28 days.
You are looking for the lowest price.

Questions

Why are there no client names on this page?

Because the companies we work with do not issue public testimonials, and asking them to would be a bad use of the relationship. What we can do is put you on a fifteen minute call with someone who has worked with us, at proposal stage, once the conversation is serious.

What if our data is a mess?

It usually is. The Scan is designed to work with exports, not with a clean data warehouse. If the data genuinely cannot support the work, we tell you in the first call and you pay nothing.

Do we need to buy anything else?

No. No software, no integrations, no licences. We work in your existing sheets and exports.

Who actually does the work?

Strahinja, on every engagement. Specialists join for specific pieces when the engagement needs them.

What happens after 28 days?

You own the system and the rulebook. Thirty days of async support are included. Some clients move to a monthly retainer. Most do not need to.

Why is the media plan involved at all?

Because it is the only forward looking demand signal in the business. Sales history tells you what happened. The media plan tells you what is about to.

What if we do not have a formal media plan?

If you know roughly what you intend to spend by channel over the next quarter, that is enough. It does not need to be a document.

Can we start with the Sprint and skip the Scan?

No. We do not quote a Sprint without seeing the numbers first, and you should not accept one from anybody who does.

We plan your inventory off your media plan, not last quarter's sales.
