## Key points

- PropExecutor plans are one-time payments from $129, with no setup fee, no monthly platform fee and no revenue share.
- A new prop firm does not need a broker-shaped platform because PropExecutor is a purpose-built simulator.
- Each account costs one credit regardless of simulated balance, and credits never expire.
- PropExecutor includes a branded terminal, a tick-level rule engine, an admin panel and a built-in CRM on every plan.
- The API, webhooks and WebSocket events are included on every plan to automate repetitive work.

A new prop firm has a short list of jobs: sell evaluations, serve traders and grow. Most early money goes somewhere else. It goes into infrastructure and recurring bills built for other businesses. Here are the five mistakes that drain a founder's budget, and what to do instead.

## Mistake 1: Starting with a platform built for brokers

MetaTrader 5 and cTrader are strong products. They were made for brokerages, and their pricing and setup fit that market. A new prop firm does not need to run a brokerage stack. It needs simulated accounts, rules and a terminal traders enjoy.

When a founder buys a broker-shaped stack, the budget goes to infrastructure before the firm has a single trader. That is the root of the other four mistakes.

## Mistake 2: Accepting a bill that never stops

Monthly fees feel small at first. Over a year they become the biggest line in the budget, and they arrive whether or not you sold a challenge that month.

PropExecutor works the other way. Plans are one-time payments, with no setup fee, no monthly platform fee and no revenue share. Credits never expire, so a slow month costs you nothing extra.

| Plan | One-time price | Accounts | Per account |
|---|---|---|---|
| Starter | $129 | 50 | $2.58 |
| Basic | $499 | 250 | $2.00 |
| Professional | $829 | 500 | $1.66 |
| Growth | $1,799 | 1,250 | $1.44 |

The money you keep can go to marketing and to running the firm. See the full breakdown on the [pricing page](https://www.propexecutor.com/pricing).

## Mistake 3: Paying for what the account size implies

Some founders assume a bigger simulated balance costs more. On PropExecutor it does not. A $5K account and a $100K account each use one credit. Each trading account created uses one credit permanently, and breaching or archiving it does not refund the credit.

That makes planning simple. Count the accounts you expect to sell, pick the plan, and add top-up packs of 100, 500 or 1,000 accounts at your plan's per-account rate when you need more.

If you outgrow a plan, you buy the higher plan at full price and receive its full credits. Unused credits carry over.

## Mistake 4: Piecing together tools instead of using one platform

A founder who builds from parts ends up with a terminal, a rule script, a spreadsheet of traders and a dashboard, all paid for separately and all needing upkeep. Every part is another bill and another thing to break.

PropExecutor includes the pieces in one place:

- A branded web trading terminal with watchlist, chart, order ticket, positions and history.
- A live view of each account's rule headroom.
- A rule engine that judges every account on every price tick, with daily loss, maximum loss, profit target, trailing drawdown and more.
- An admin panel that creates up to 5,000 accounts at once.
- A built-in trader CRM on every plan.

Orders are simulated against live prices for 50+ instruments, including forex, gold, oil, indices, Bitcoin and Ethereum. You can read more about the [rule engine](https://www.propexecutor.com/prop-firm-rule-engine) and the [feature set](https://www.propexecutor.com/features).

## Mistake 5: Launching without your own brand

Traders trust a firm that looks like a firm. A terminal with someone else's name makes yours look borrowed.

PropExecutor is white label. You set your firm name, logos, colours, login screen and support links. Starter covers the firm name, dark logo and accent colour. Basic gives full branding. Professional and Growth also hide the PropExecutor badge. The terminal can also run on your own domain.

## What a sensible first budget looks like

Put the platform at one fixed payment, then spend the rest on the firm. With the Starter plan at $129 you get 50 trading accounts, a branded terminal and the rules to run them, on Google Cloud infrastructure built to scale with your traders and traffic.

As you grow, the API lets your systems do the repetitive work. It is included on every plan. Your backend can assign traders by name and email, read trades, positions and rule flags, and rotate credentials. Webhooks tell you when an account breaches or passes, and a WebSocket API streams account events in real time. Accounts themselves are created in the admin panel, then your backend assigns them to buyers. The [API docs](https://www.propexecutor.com/docs) show how.

## The takeaway

The mistake behind all five is spending on infrastructure shaped for someone else. A purpose-built simulator with a one-time fee lets you put your attention on the firm and the traders.

Try the live demo from the website, then review the [pricing](https://www.propexecutor.com/pricing) and pick the plan that fits your first batch of accounts.

## Frequently asked questions

### Do I need MetaTrader 5 or cTrader to start a prop firm?

No. PropExecutor is a simulator with its own branded terminal, so a new firm does not need a broker-style stack. Orders are simulated against live market prices for 50+ instruments. Many founders find this removes the largest early costs and lets them focus on traders.

### How does PropExecutor pricing work?

Plans are one-time payments, with no setup fee, no monthly platform fee and no revenue share. Starter is $129 for 50 accounts, Basic $499 for 250, Professional $829 for 500 and Growth $1,799 for 1,250.

### Do I pay if I sell fewer challenges one month?

No. Credits never expire, so unused ones stay in your balance. Each trading account uses one credit permanently. This means slow months cost you nothing extra and you can plan purchases around real demand.

### Can I add more accounts later?

Yes. Top-up packs of 100, 500 or 1,000 accounts are sold at your plan's per-account rate. You can also upgrade by buying a higher plan at its full price, and your unused credits carry over.

### Can I put my own brand on the terminal?

Yes. You can set your firm name, logos, colours, login screen and support links. Starter covers the firm name, dark logo and accent colour. Basic offers full branding, and Professional and Growth also hide the PropExecutor badge.

### Can I automate the firm with an API?

Yes. The REST API is included on every plan. Your backend can assign traders, read trades and rule flags, and rotate credentials. Webhooks announce breaches and passes, and a WebSocket API streams account events. Accounts are created in the admin panel.
