Well, first of all, the easiest way for you to present a more realistic picture of your Company's financial position is to have your financial statements prepared by a CPA in accordance with Generally Accepted Accounting Principles, on the accrual basis, rather than on a tax basis which is on the same basis as how your tax returns are prepared.
That will reflect your equipment as an asset and subject to depreciation rather than being expensed under IRC 179 for tax purposes.
Also, you are most likely on the cash basis, which disregards ***** ***** assets that you may have not yet realized such as Accounts Receivable, possibly other items of continuing value such as prepaid insurance, etc.
Further, realize that when you say that you could leave $150k in the "coffers" rather than taking a large distribution, that would be the way to re-invest into the Company as of your Balance Sheet date, not taking the distribution as you say that you would "rather re-invest it into the Company". You would only have to leave it there as of your Balance Sheet date to strengthen your Balance Sheet at that point; not a permanent investment in the Company.
As you are approaching $1,000,000. in revenue, as a service oriented company, you really should have accrual basis financial statements which is the norm as your Company begins to mature, which is certainly the case after 11 years in business. A 250K of profit on less than $1,000,000. in revenue, is indicative of a very successful business, and you should not have any problem obtaining a reasonable business line of credit. Banks do not like to lend money to S-Corp's so that the owner-employee can withdraw the profits (that's the way they look at it), rather than leave sufficient equity in the Company to provide ongoing working capital.
